[00:00] david__: what i said was, it depends on what you are doing [00:01] lets say for example [00:01] you lay down guitar [00:01] then, you overdub vocal on it [00:01] and you have 60ms latency [00:01] aroudr *should* compensate when you are overdubbing and line everything up [00:01] ardour* [00:01] Got it. [00:01] you can and should test for that [00:02] *IF* you have a keyboard [00:02] I do [00:02] some USB keyboard, or midi controller [00:02] you hit the key [00:02] 60ms later the sound comes you [00:02] thats not going to be acceptable [00:02] but, niether is 20ms [00:02] if you have an internal sound card, you really cant expect much out of it [00:11] Thank you holstein. I saved a copy of this chat so I can refer back to it. [00:11] david__: :) [00:12] JACK is *not* trivial to get running [00:12] I might check on abgogani's ppa in the future (maybe next weekend) [00:12] but, its quite versitile [00:12] (and see what I can get out of the internal sound card) [00:16] well, its not so much what you get out of it, its what folks potentially put into the machine through them [00:16] but, if you are working with MIDI, you'll be ahead of the curve in that regard [00:18] Any experience with recovering corrupted Ardour projects? [00:18] (It's not going well) [00:21] david__: sure [00:21] the audio should just be there [00:21] the fles [00:21] files* [00:21] otherwise, ask around #ardour [00:22] Okay I'm looking through the files (It looks hopeful) [00:22] But I can't hear them in Audacious [00:23] (The meter bars are jumping) [00:23] i have no idea how your sound is set up [00:23] try a player you are familiar with [00:23] install audacity and import [00:24] ues VLC [00:24] use* [00:24] Sound was working with Rosegarden and MIDI keyboard [00:24] david__: cool [00:24] dont live in the past though [00:24] you'll need to actually troubleshoot whats going on there [00:24] my first suggestion is to try anther player [00:24] I would need to install all the programs you mentioned [00:24] VLC [00:25] sudo apt-get install vlc [00:27] I installed VLC [00:27] Same issue with sound [00:27] (no sound) [00:31] Thanks for your help, got to go eat. === falktx__ is now known as falktx [01:33] Is there a troubleshooting guide to get audio playback on Ubuntu Studio? [01:33] I'm not seeing anything on [01:33] https://help.ubuntu.com/community/UbuntuStudio [01:33] Ardour playback works, but not VLC or Audacious [01:34] david__: its complicated [01:34] theres a general audio one, and that works [01:35] https://wiki.ubuntu.com/DebuggingSoundProblems [01:35] david__: could be that VLC/audacious are expecting JACK [01:36] I've tried with and without JACK running [01:36] could be that when you started ardour, JACK stared, and VLC/Audacious are expecting pulse [01:36] could be that JACK is still running somewhere in the background [01:37] I stopped and quit JACK but still the same [01:37] (I used QJackCtrl [01:40] david__: it could still be running in the background [01:40] you can run top and look [01:40] you can restart to be sure [01:40] you can just try sudo killall jackd [01:41] david__: audacious has JACK output [01:41] you can check in it, and see [01:41] you should be able to tell it to use JACK while you have the file playing in ardour or whatever [01:43] I just tried sudo killall jackd [01:43] It said "jackd: no process found" [01:44] i think its called something else now [01:44] you can open a terminal and run top [01:44] I've not used top before [01:44] http://www.cyberciti.biz/faq/show-all-running-processes-in-linux/ [01:44] I don't really undersand it [01:44] right [01:45] you can always just restart to be cure [01:45] sure* [01:45] then, JACK is not running [01:45] you can start simple [01:45] start with audacity [01:45] start with VLC [01:45] will do. [01:45] I'll download and install audacity first [01:45] sudo apt-get install audacity [01:45] its in the repos [01:46] check out #opensourcemusicians too === david is now known as Guest84829 [01:55] holstein: After I restart it reloads all the programs I was using from before, so I'm not sure it is a good way of zapping JACK (If indeed it is still running) [01:56] it? [01:56] I presume Xfce did it. [01:56] if you are using XFCE, and you choose to 'save session' at the end, thats what you get [01:57] the session saved and relaunched [01:57] that'll take some getting used to when i suggest restarting ;) [01:57] read that link though, and just see if jack is running or not [01:57] http://www.cyberciti.biz/faq/show-all-running-processes-in-linux/ [02:01] I actually had the "save session" unchecked the second time and but it still restarted everything, but no matter I am looking through the ps | less list [02:03] It's a long list, but I don't see anything called JACK [02:05] i wouldnt expect to sort it out in one night [02:05] JACK is *not* trivial [02:06] also, there might be codecs you need to play an mp3 for example [02:06] Just WAV [02:07] (plus I assume VLC can play anything on Linux like it can on Windows ) [02:07] david__: did i say assume nothing? [02:07] maybe that was someone else... [02:07] anwyays, whats the problem? [02:07] you cant get anything but ardour to play the .wavs from a broken session? [02:08] have you tried other audio? [02:08] something in the browser? [02:08] http://dl.dropbox.com/u/1172535/groove.ogg should play in the browser [02:10] No luck with the browser (firefox 8) [02:10] david__: what works? [02:10] and what doesnt? [02:10] now you have no audio at all? [02:10] Ardour playback works [02:11] OK [02:11] thats JACK [02:11] perdiod [02:11] ardour uses JACK [02:11] so, JACK is running [02:11] and pulse is suspended then [02:11] MIDI keyboard through Rosegarden [02:11] That was before I restarted [02:11] so, *nothing* will play except in JACK right now [02:11] david__: ? [02:11] what about now? [02:11] right now [02:11] this minute [02:11] Sorry [02:12] Let me try ardour again [02:12] (Is that what I should do?) [02:12] david__: sounds like a plan [02:15] Ardour (without starting JACK first) does not playback [02:15] But it does record [02:16] Audacity same thing (records, but no playback) [02:16] i would go as far as suggesting to you to make a new user account, log in there, *dont* start JACK, and mess with the audio [02:16] just normal stuff [02:16] playing files [02:16] make sure the sound works at all [02:18] I'll try, see you on the other side :) [02:24] holstein this is is david__ again [02:24] no luck with the new accound [02:24] *account [02:24] in what way? [02:24] no sound? [02:24] no sound [02:24] maybe you have no sound [02:24] maybe you have something muted [02:24] maybe its something in alsamixer that JACK bypasses [02:26] The system volume is max and the VLC volume is 100% [02:26] How do I view the alsamixer? [02:26] guest-UGFWFC: also, install pavucontrol [02:26] i find it helpful [02:26] guest-UGFWFC: you can open a terminal, and run.. [02:27] alsamixer [02:27] and/or [02:27] sudo apt-get install pavucontrol [02:29] It looks like I can't sudo from this user account [02:29] guest-UGFWFC: control+alt+F7 will get you back where you are [02:29] AlsaMixer shows Master 100, Headphon 100, Speaker 71 [02:29] you can do control+alt+F1 [02:29] and you can sudo install, or sudo add yourself to the sudoers [02:30] OR, you can just go back, since we kind of know what it is now [02:30] guest-UGFWFC: dont trust any of those labels [02:30] i would go back to the other account [02:30] install pavucontrol [02:30] and see if you can sort it out from there [02:42] Is there an UbuntuStudio equivalent to: "Go to System > Preferences > Sound ("Multimedia Systems Selector" in earlier editions of Ubuntu) [02:43] (I'm working through https://wiki.ubuntu.com/DebuggingSoundProblems ) [02:45] @holstein: sorry I pressed Ctrl+Alt+F1 and wasn't able to get back to the desktop, so I had to switch the computer off and start over [02:57] david__: its the same [02:57] its just not gnome2 anymore [02:57] david__: control+alt+F7 returns [02:57] you can sudo reboot from there if needed [02:57] try install pavucontrol [02:58] that is similar to multimedia system selector [03:03] I ran pavucontrol (turns out it was already installed) [03:03] Everything is at 100% [03:04] ok [03:04] david__: so, open a terminal [03:04] run this [03:04] aplay -l [03:05] when you see output about your card, then you know you *should* be getting sound [03:05] if you dont, then, your card is not being recognized by alsa or something trickier [03:05] if you see if listed there as a playback option, then you know its something fiddly like what i am talking about [03:05] Yes it lists information [03:05] david__: you can also just install main normal ubuntu [03:06] if that is what you are comfortable with [03:06] ubuntu = ubuntustudio = xubuntu etc... [03:06] there are just some pre-configured packages that you might be more used to in normal buntu [03:06] I was using Ubuntu last week but I broke it (ardour stopped working on Ubuntu main) [03:07] david__: OK [03:07] that sounds related to me, no? [03:07] maybe your sound card is dying? [03:07] gosh, I hope not [03:07] Windows is fine [03:07] either way, i personally would disable it in the bios and get something more appropriate [03:07] http://www.behringer.com/EN/Products/UCA202.aspx [03:08] ^^ thats like 20 bucks US [03:08] less hassle [03:08] better latency [03:08] cleaner signal [03:08] anyways... [03:08] that all sound related to me.. maybe its something with the latest kernel and your hardware [03:08] david__: have you checked for, and applied all upgrades? [03:09] Yes, I applied all updates [03:09] david__: im not kicking you out of here, but... [03:09] does the "U-control" support MIDI? [03:09] you can also try #ubuntu, #ubuntu-beginners [03:09] #xubuntu [03:09] understood [03:09] #opensourcemusicians [03:09] this is really *not* ubuntustudio specific [03:09] you can cast a wider net in the #xubuntu pool [03:10] or general buntu channels [03:10] Except I'm using a fresh install of UbuntuStudio [03:10] but, if i want an audio rig, i *never* use the internal card [03:10] david__: yeay [03:10] with upgrades applied [03:10] ubuntustudio = ubuntu [03:10] same kernel [03:10] same alsa versions [03:10] same pulse [03:10] if you applied an upgrade that broke soething ubuntu main ubuntu [03:11] that same thing will happen with ubuntustudio [03:11] or ubuntu [03:11] or xubuntu [03:11] whatever... [03:12] Sound worked on Ubuntu main just Ardour was broken [03:12] (after a few days) [03:12] use) [03:13] yeah, and that makes no sense [03:13] you use JACK for a few days, and break it? [03:13] how? [03:13] what did you do? [03:13] why did you leave it? [03:14] whatever is going on, you have some trouble shooting to do [03:18] It stopped working during normal use (switching between Rosegarden and Ardour). After troubleshooting for a while I hoped a fresh install would help, but I ended up with different problems. [03:18] yup [03:18] its a drag [03:18] david__: i think you should get the LTS === david is now known as Guest87446 === davidb is now known as Guest55094 [04:01] holstein: I was able to get Ardour working on the regular Ubuntu (it was still installed on a separate partition) [04:02] It was some corrupt Ardour files causing a problem
