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

| dbolton | holstein: I was able to get Ardour working on the regular Ubuntu (it was still installed on a separate partition) | 04:01 |
| dbolton | It was some corrupt Ardour files causing a problem | 04:02 |
