[04:22] hi studio channel, i have a bizarre issue [04:25] i cant seem to get my audio interface to work with 15.10, running 4.2 kernel. this particular interface (Focusrite Scarlett 18i20) is allegedly supported since kernel 3.19. Anyways, after a week of troubleshooting and researching it SEEMS that laptops with intel HDMI ports have an issue where ALSA/pulseaudio prioritizes the HDMI's playback over any other soundcard. So... simple enough I figured I would blacklist the HDMI [04:25] driver (snd_hda_intel according to the output of lspci). Except when I do this alsamixer no longer works (typing alsamixer into the terminal gives me a "command not found" output. Anyone here got a suggestion? Ive spent all week on this problem, and all I want is to record some music :(:(:( [04:44] benjidass: that sounds wierd. [04:45] benjidass: I would try unblacklisting that module... Though I am sure I have run without it before. [04:46] alsamixer should not be tied to HDA anything. [04:47] anyway, if pulse is a problem, I have found running pavucontrol and in the config tab turning all the profiles off works for me. [04:48] ovenwerk1: could you please elaborate? (and yes, you have no idea how weird it is. it seems like this interface is just plug and play for everyone in the world but me...) [04:50] have you started pavucontrol? [04:52] no, it is an application? [04:52] yes [04:52] ovenwerk1: i am installing it right now [04:52] you shouldn't have to [04:52] oooh [04:53] ovenwerk1: it is just sound preferences :P [04:53] which OS do you have? [04:53] Ubuntu Studio 15.10 [04:53] probably [04:53] sound settings [04:53] overnwerk1: we spoke i think last sunday on the #ardour channel. I have spent all week on this problem :( [04:54] we go slow and see if one step at a time will get there [04:54] ovenwerk1: so you see, under "pavucontrol" my Scarlett is recognized as a "Multichannel Input" device, no playback. [04:54] ovenwerk1: okay, one step at a time sounds great :) [04:55] first lets just turn them all off. [04:56] overwerk1: okay all devices are "Off" under the Configuration tab [04:57] ok, I think you have seen this before :) but lest try again... [04:57] cd /tmp && wget http://jackaudio.org/downloads/adevices.sh && bash ./adevices.sh [04:57] and paste the output. [04:58] (to pastebin [04:59] http://pastebin.com/Jg5ZD2Un [05:00] ok, there is both input and output shown. Good [05:01] I am going to do commandline stuff for a bit. [05:01] right, alsa totally recognizes all the channel [05:01] go for it [05:02] jack_control ds alsa dps capture none dps playback none [05:02] run the whole line [05:02] nothing much will happen [05:02] http://pastebin.com/8XbuUpcC [05:04] jack_control dps device hw:usb dps rate 48000 dps period 1024 dps nperiods 3 start [05:05] then: jack_lsp [05:05] http://pastebin.com/5gmvLy2K [05:06] and this is just the output for "jack_lsp" [05:06] http://pastebin.com/4DWvz1DG [05:06] ya, I had guessed that [05:07] so now is the magical moment where you give me the ultimate solution? :P [05:08] tell me about the leds that are lit on the focusrite [05:08] "USB Active" and "Locked" and "Power" [05:08] right half of the front pannel. [05:08] right [05:08] if i play music the channel one input led's respond as well [05:09] yes [05:09] well, channel one being the only channel with any inputs at the moment [05:09] that all sounds good [05:11] It likes everything except the start [05:11] does jack_control exit work? [05:12] as in, type "jack_control exit" into the terminal? [05:12] yes [05:12] it says "--- exit" [05:12] so it seems like it works to e :) [05:12] me* [05:12] right good [05:15] Ahh, maybe I got the device wrong. [05:15] try jack_control dps device hw:USB dps rate 48000 dps period 1024 dps nperiods 3 start [05:15] notice USB is all caps [05:17] http://pastebin.com/jNeBTdGJ [05:17] yes sir, noted [05:19] cat .log/jack/jackdbus.log [05:20] just paste the very last screen [05:21] uh [05:21] do you mean ./log/jack/jackdbus.log? [05:21] bc I got "no such file or directory" [05:22] ~/.log/jack/jackdbus.log [05:23] http://pastebin.com/rhfgGAEf [05:23] (I forgot you are in temp) [05:23] let me know if that's not enough output [05:23] (no problem, i appreciate your patience and help) [05:24] Thats prlenty [05:24] *plenty [05:24] It shows the same thing as pulse inouts work outputs don't [05:24] EXACTLY [05:25] So lets try treating it like two devices. [05:25] i can open an ardour project with the scarlett selected as the input device, but when I select it as input AND output it fails [05:25] okay sounds good (if you tell me how :) ) [05:26] jack_control dps capture hw:USB dps rate 48000 dps period 1024 dps nperiods 3 start [05:26] should start things with just inputs [05:28] not quite... [05:28] http://pastebin.com/QCS58iJr [05:29] zita-j2a -j USB-out -d hw:USB -r 48000 -p 512 -n 3 & [05:29] oh stop don't do that [05:29] lol alright [05:29] what was the last page of the jack log now? [05:29] let me see [05:30] http://pastebin.com/5JxHXL7z [05:31] ok, it is remembering the device from before :P [05:31] jack_control ds alsa dps capture none dps playback none [05:32] do you want the output? [05:32] then jack_control dps capture hw:USB start [05:32] Not unless there is an error [05:32] non errors [05:33] both lines? [05:33] now there is an error [05:33] http://pastebin.com/08fMVmZE [05:34] thats the input and output for the last two commands [05:34] does the log still show it trying to do a playback? [05:35] it seems like it just has a bunch of "cant connect to server errors" [05:36] http://pastebin.com/a8JYyWZD [05:37] bash ./adevices.sh [05:37] again [05:38] http://pastebin.com/zZc8diwB [05:39] WT? makes no sense. [05:39] jack_control exit [05:40] i know :( i have no idea what to do [05:40] exiit complete [05:40] jack_control ds alsa dps capture none dps playback hw:USB start [05:41] http://pastebin.com/38Q1cvr9 [05:42] lets have some other fun...

[05:44] i figured shit would work fine my internal sound card [05:46] my mistake [05:46] jack_control ds alsa dps device hw:PCH dps rate 48000 dps period 1024 dps nperiods 2 start [05:47] http://pastebin.com/aqRftjSY [05:47] if no errors jack_lsp [05:47] nope, still errors. [05:48] end of log file? [05:48] http://pastebin.com/d0NSRCs0 [05:51] this is a clean install by the way. earlier this week I tried avlinux and it didnt fix shit, so I came back to ubuntu studio. and I dont think the unit itself is flawed bc I plugged it into a windows box and had no problems at all :( [05:51] ok it looks like it has not stopped trying to get USB (wierd) lets try dropping evreything first. [05:51] sounds good to me [05:52] jack_control ds alsa dps capture none dps playback none [05:52] then: [05:52] okay no errors [05:52] jack_control dps device hw:PCH dps rate 48000 dps period 1024 dps nperiods 2 start [05:52] again [05:53] ah hah [05:53] no errors [05:53] you want the output? [05:53] jack_lsp [05:53] not if no errors [05:54] jack_lsp should show captures and playbacks [05:54] yes it does [05:54] want it? [05:54] http://pastebin.com/3f6RAWvB [05:54] zita-j2a -j USB-out -d hw:USB -r 48000 -p 512 -n 2 & [05:55] says "Can't open ALSA playback device 'hw:USB'." [05:55] and actually, its hanging. doesnt send me back to a command line prompt [05:56] zita-a2j -j USB-in -d hw:USB -r 48000 -p 512 -n 2 & [05:56] hit enter [05:56] it has probably over writen your prompt [05:57] i hit Ctrl+C, hope thats not a problem [05:57] ok [05:57] try the other line [05:57] trying it [05:57] so far it says "Starting synchronisation" and just hanging... [05:58] thats ok [05:58] hit enter [05:58] okay thats all the output it gave [05:58] now look at jack_lsp again [05:59] the same with 2 capture tracks on the USB [05:59] http://pastebin.com/wWYFW4nr [05:59] right I forgot it defaults to 2 channels [05:59] but it shows the same thing [06:00] capture works and playback does not [06:00] right, I see no playback channels for the USB device [06:00] That line failed. "Can't open ALSA playback device 'hw:USB'." [06:00] i do see PulseAudio "sink" and "source" channels but I cant tell where theyre going [06:01] they are by default connected to your internal outputs and inputs. [06:01] wait which line? [06:01] zita-j2a -j USB-out -d hw:USB -r 48000 -p 512 -n 2 & is the fail. [06:01] the "zite-j2a" lines failed, but the a2j command didn't give any errors [06:01] right right [06:02] ALSA sees the playback ports but can not let anything open it. [06:04] but you see, when I try to open an Ardour project with HDA Intel selected as the playback device, it doesnt complain. So ALSA can playback through the internal card just not the scarlett's playback channels [06:06] changing the zita-a2j to have a -c 30 in there will give you all the input channels. [06:06] (you would have to kill the one running first) [06:08] so "killall zita-a2j" followed by the above zita command? Can I insert the -"c 30" anywhere in the command? [06:08] should be able to. [06:10] oh shit [06:10] this might be good [06:10] it is hanging again though [06:10] should I just hit enter? [06:10] yes [06:10] uh... no matter how many times I hit enter it is still hanging [06:11] in a second terminal does jack_lsp show the ports? [06:11] it says "Warning: only 18 channels are available. [06:11] Starting synchronisation: [06:11] right [06:12] That should be ok. [06:12] oh [06:12] my [06:12] god [06:12] I have used -c 100 [06:12] wait [06:12] it shows all 18 capture tracks for the USB-in device [06:12] but still no capture [06:12] well i guess that makes sense, we used "USB-in" [06:15] im sorry, i meant "still no playback" [06:15] its late for me :) [06:16] me too [06:17] You can use it that way... with internal for out.... but I would like to know what the real problem is [06:19] so would i :) [06:19] but what do you mean by "with internal for out"? [06:20] you can run the way it is set up right now with internal sound for out and USB inpouts [06:21] oh, yeah I could... but part of the reason I dropped money on this big old box was so I could use the extra outputs for outboard effects :( [06:21] I am not sure if the trouble is kernel or alsa [06:22] if it works with windows, then it has to be one or the other [06:22] i dont think its the kernel bc I tried installed low latency 3.19 and got the same problem. I then compiled 4.4 from scratch and installed that, still got the same problem [06:23] Have you tried it with other physical USB ports? [06:23] im pretty sure at thsi point the problem is a combination of pulseaudio and my specific hardware (this stupid HDMI port that I have never used) [06:23] Is it by chance sharing an internal USB hub with something else? [06:23] i have tried both USB ports on my laptop. [06:24] if it is sharing anything internally I do not. I am even stupider when it comes to hardware [06:24] I do not know* [06:24] is there a way to tell, via lspci maybe? [06:24] My netbook had two USB on the right and one on the left. I always had trouble with th eone on the left, but either one on the right was fine so long as the other one on the right was not used. [06:25] It is not pulse. [06:25] the only thing plugged into my external USB ports right now is the Scarlett. and I only have 2 ports on the laptop [06:25] it is ALSA or kernel [06:25] but pulse handles all the playback for ALSA, no? [06:25] no [06:25] oh, psh nvm [06:25] apparently I have learned nothing this week :P [06:25] and we told pulse not to grab the alsa ports. [06:25] oh okay [06:26] That was why we turned all thge profiles off [06:26] wait. but when I run jack_lsp I still have PulseAudio sink and source channels... [06:26] yes pulse is using jack as its audio device. [06:26] oh okay okay [06:28] In my case I actually unload the pulse module that detects new audio devices. [06:28] you use a Scarlett yourself, correct? [06:28] no [06:28] oh nvm [06:28] delta66 [06:28] oh okay [06:29] I do have a 2 channel USB box for my wifes computer though. [06:29] Gotta go family needs me. [06:29] no problem, appreciate all your help [06:29] have a good one === ezri is now known as rw [06:46] ovenwerk1: btw, i will keep the IRC client open, so if you have any other ideas feel free to drop a post, and I will check it when I I wake up in the morning. Again, I really appreciate your help. Have a good night. [13:14] hi everybody! my network indicator disappeared from the status bar, what can i do? [13:40] sup [13:40] hi everybody! my network indicator disappeared from the status bar, what can i do? [13:43] sancho_panza: Hi. You can try in #ubuntu as well there, more eyes. === sat-buddhi is now known as advaitasiddhi [13:44] does ubuntu studio runs xfce? [13:44] Yes. [13:45] But the indicator is the same. [16:29] I recently tried to configure Plex media server on my ubuntu. Plex was finally able to display the folder containing media files. But after shut down my Ubuntu boots to Emergency mode. What I did was put the Ubuntu Live USB and then as a root user commented out the changes in the fstab that i made earlier while configuring Plex. Now Ubuntu boots no [16:29] rmally again. But is there any way I can configure plex and boot normally next time I shut down. I must have messed up something in the fstab :P [16:29] i followed these instructions from askubuntu forum to configure the fstab : https://dpaste.de/jkfS [19:27] pretty excited to have discovered this. [20:01] my mother enters the room, sees GLMatrix screensaver on the CRT monitor, asks "what's that" >:) [20:35] Has anyone tried using bitwig with ubuntu studio? [20:51] Kimryd: The demo at least works. [20:51] OvenWerk1, I own bitwig and used to use it on windows, but I can't seem to get jack working?\ [20:54] I am using it with jack ok. but it should work with straight ALSA ok. [20:58] Kimryd: how is jack "not working"? bitwig doesn't see it? bitwig gets no audio? [20:59] OvenWerk1, http://imgur.com/a/dJCmo [20:59] That's what jack shows me [20:59] BUT [20:59] Renoise works fine [21:00] Kimryd: you need to start jack before starting bitwig [21:00] on qjackctl there is a start button [21:01] I did that too :{ [21:01] Bitwig won't show up in the connect no matter how I start stuff up [21:01] hrm [21:01] I'll install the RC and see if anything different happens [21:01] so stop bitwig, [21:02] in a terminal do killall -9 jackd jackdbus [21:02] done [21:02] Then use qjackctl to start jack. qjackctl connections should then show your sound card [21:03] if so then start bitwig [21:03] Started and starting [21:04] And bitwig is up and the same, it's very perplexing [21:04] would the messages window give me more info? [21:04] when I open bitwig preference-> Audio, I see a lot more boxes/buttons right below the driver box. [21:05] Yeah, I don't! That's what I'm finding super weird [21:05] Shouldn't there be 3 boxes under the "Jack" one? [21:05] One for in/out/something [21:05] I have four. [21:06] odd [21:06] input output SR buffer [21:06] Renoise works like a charm so something in bitwig must be the issue [21:07] my bitwig version is 1.1.6 [21:07] I'm on 1.3.6 [21:07] very interesting indeed [21:08] lets try ALSA just for fun [21:09] I think you need to change the device before shutting BW down. Then exit bitwig. [21:09] then hit the stop button in qjackctl [21:10] open pavucontrol [21:10] in the configuration tab go to the profile for the audio device you are using and turn it "Off" [21:10] then try starting BW and setting the ALSA device [21:14] Sorry OvenWerk1 was handling something, trying now [21:16] It shows none in the ALSA driver OvenWerk1 [21:17] At which point? [21:17] (step) [21:17] In audio system [21:17] In bitwig [21:17] I select alsa as driver model [21:17] and the second box shows "None" with no options to change [21:18] Right because jack or pulse might still be using it. try again at the end after stopping jack and turning pulse off for that device [21:19] do I terminate/kill pulseaudo --start in the task manager? [21:20] Kimryd: you shouldn't have to. [21:20] When I switch to ALSA, input and output say none, but when I click on them there is a drop down that lists devices. [21:21] It shows devices nots used jack or pulse and pulse itself. [21:24] OvenWerk1, is there some kind of log for bitwig I can check? [21:25] Kimryd: I'm not sure [21:26] ~/.BitwigStudio/bitwig_studio.26692.log ? [21:27] The number may be different [21:27] not much in there [21:28] engine.log in the same directory has slightly more [21:30] ls [21:31] Sorry I haven't used Linux since I was 16 lol [21:31] A bit tricky navigating the file system [21:32] ~/ means your home directory. .BitwigStudio is BW's config directory [21:33] the dot in front of BitwigStudio means it will not show up in your file manager unless you select show hidden files. [21:33] found it [21:33] Found an error [21:34] opt/bitwig-studio/bin/BitwigStudioEngine: error while loading shared libraries: libxcb-icccm.so.4: cannot open shared object file: No such file or directory [21:34] In the engine.log file [21:34] Because starting the engine itself is the whole problem here [21:36] maybe try sudo apt-get install libxcb-icccm [21:37] which version of ubuntu are you using? [21:37] the LTS one [21:37] 14.04? [21:37] sorry, it should be sudo apt-get install libxcb-icccm4 [21:38] or you can use synaptic [21:40] ya I have ubuntustudio 14.04 and I have libxcb-icccm4 installed... I don't know if Studio came with it or I added it later [21:41] I have been running 14.04 for over two years now since it went alpha and have done lots of stuff with it including dev work, so it is hard to know what was there an d what I have added [21:44] I see I See [21:44] I apt-gotted [21:44] Lets see what hapens [21:45] OvenWerk1, is qjack tied to LADI? [21:46] Can be, not here though. [21:46] o [21:46] * OvenWerk1 knows about nothing with Ladi [21:46] my [21:46] god [21:46] bitwig's engine started [21:46] * Kimryd hallelujahs [21:46] :) [21:46] * Kimryd praises lord linux [21:47] Thank you so much OvenWerk1 [21:47] If you hadn't pointed me at that log [21:47] it should work with jack now too. [21:47] Yep [21:48] I still only have 1 box for the jack driver, but the engine is running [21:48] Bitwig is jacked up in the connections too [21:48] It was the libxcb [21:48] I don't even know what that is though [21:49] It says it is an extension lib for x. So display stuff nothing to do with audio. [21:49] T_T [21:49] That's stupid [21:49] Wonder why it was causing problems [21:50] I am not sure. It could be communications related. Talking to dbus or something [21:51] both jack and pulse use dbus [22:01] Hi [22:02] Hello [22:03] Anybody knows if UbuntuStudio uses a generic kernel or rt or lowlatency? [22:05] In AskUbuntu page have told me that now uses the generic kernel. I thought he was using the Low Latency [22:17] maique: You were thinking right. [22:18] maique: so far as I know we are still using a lowlatency kernel [22:18] ok, thank you [22:19] /boot/vmlinuz-4.4.0-8-lowlatency in 16.04 [22:20] The truth, I find it strange the response from Ask Ubuntu [22:20] told me that the difference is only the software... [22:21] the difference from generic to lowlatency is very small, just a few settings before compile. [22:21] but they do make a difference for live softsynth or effects work. [22:21] ok [22:22] I asked if there is a minimal installation of Ubuntu Studio (as there is a Ubuntu minimal iso) [22:22] But it is close enough to the generic kernel so that the graphics "blobs" from nvidia still work [22:24] mini.iso (or is it net.iso) can install studio. I am not sure which kernel(s) you will end up with, but part of our setting package makes sure that a low latency kernel is always default [22:24] (even if there is a newer generic) [22:25] I would like to install Ubuntu Studio minimal. And then install programs manually (and off-line) It this posible? [22:25] maique: our meta packages/menus/etc can be installed on top of any ubuntu flavour. [22:27] There is no ubuntustudio minimal. However, the ubuntustudio installer allows you to choose which packages to install. Off line means you would need to already have alll the packages locally... so that is not very minimal. [22:28] okay Ovenwerkl, thank you :-) [22:28] maique: what are you trying to achieve? [22:28] Which packages are you trying to avoid? [22:29] Simply I wanted to have a base installation (no programs ). And also be able to install them later without internet connection. [22:31] Being able to install the base on a computer without internet. Install each program (Synfig, Inkscape, Gimp etc .... always the latest version) from a flash drive. [22:31] I have never tried installing with les packages and then adding them from the iso later, so I honestly do not know if that will work. [22:31] What kind of linux plugs can bitwig run? [22:31] If you have the packages on a flash drive you can do that manually. [22:31] Kimryd, ask bitwig?? [22:32] It only mentions LV2 [22:32] this is not the bitwig channel and I assume their documentation answers your question [22:33] Did you assume I checked it and didn't get the answers I want and thus asked a question? [22:33] Well, I'm newie in Linux... I know that can install soft from a pendrive (not always easy, need dependecies...). But my question was that: the minimal... [22:33] i had pretty much the same question. :) [22:34] also noob [22:34] i am also looking for the most minimal install for linux to build another thing on for usb boot... [22:34] it looks like i'm down to debian. lol [22:35] Peppernrino, maique https://sourceforge.net/projects/uck/ [22:35] ^ can build your own livusb [22:35] Hi Peppernrino, I thought I was the only :P XD haha [22:36] i was gonna try and compile it myself and use rufus to burn it [22:36] thanks Peppernrino for the link... but works with studio too? [22:37] debian or arch linux... [22:38] Kimryd: while running bitwig I only see the built in plugins as far as I can tell. I do not see where external plugins can be selected. [22:38] that was kimryd... [22:38]
