Hm... I had seen some reports online about USB audio devices not being recognized in Ubuntu 12.04. It seems I'm being bitten by this problem. Sometimes, I turn on the m-audio, and it shows up in lsusb but not aplay -l. This happened just a little while ago. The device worked fine after a reboot.
Is there a solution, other than rebooting frequently?
Thanks,
James

I wondered if anyone has tried this interface and can tell me about the latency. when used with guitarix or rackarrack, Is it good enough for live gigs?

And, after all those other problems, now the built-in audio output makes no sound at all. The only thing in between now and the last time it was working is that the computer slept ("suspend") overnight. Even a reboot doesn't fix it.
I can get sound out of my USB box, ok, but I can't take that thing everywhere just to have audio.
How do I troubleshoot the built-in audio card? I never had a single problem with it before.
I don't even know what to do now. Every day, there is some new random audio problem. I'm frustrated.

Just got a Zoom R16 last night. So, still reading the shit-awful
manual we expect from just about everything we get these days (sorry,
pet peeve!).
I did some googling and it seems that linux can read files as a mass
usb from the zoom, but not much more. Anyone with progress on this?

Right, thanks, I haven't used presets very much, but will maybe set those up.

Oh, great, I didn't realize you could turn off dbus. That's even better -- I found this morning that it's not enough to kill jackdbus (yes, the off list message suggested "killall -9 jackdbus"). I also have to hack ~/.config/jack/conf.xml before starting jack... which is getting to be pretty well insane, so indeed, dbus is way more trouble than it's worth for me.

I stand corrected, then. But, my daily-use setup is working quite well, even with pulse, so the question for me is, is it worth it to "fix" something that is "broken" only because pulse ranks somewhere between bats' intestines and dogs' do's among audio professionals? Maybe not...

Ditching Unity is one of the first things I did after the upgrade, not only because of the CPU-hungry compositing effects but also, I couldn't find anything. "User-friendly" my *** ;-> So now I'm running Gnome Classic (no effects).
Thanks everyone!

I'll be glad to use it, once the bugs are worked out. :-p
Anyway, I've just been running an old piece with 2-in, 4-out, some xruns but no audible dropouts. And device switching is working in qjackctl now, after turning d-bus off (and I don't get the annoying crash-on-shutdown that Tim B. reported some time ago).
I'm happy :)

I noticed that if I start jackd only, there's no jackdbus, but if I then
also start qjackctl and then close qjackctl (no execute scripts),
jackdbus is running and not stopped.
Jackd here is 1.9.8~dfsg.1-1ubuntu1. There's no other version available.
My Precise is up to date, jackd and qjackctl aren't self-compiled, but
from the repositories. Qjackctl is from Precise (0.3.8-1) and not from
Precise-backports (0.3.9-2~ubuntu12.04.1).
Ciao,
Ralf
James,
to ease with qjackctl usage, maybe you can setup 3 presets, one for each
of your scenarios with the following settings:
Preset Name Interface Input Device Output Device
---------------- --------- ------------ -------------
Away_from_Studio hw:0 (default) (default)
Need_Quality_Mic hw:1 (default) (default)
Need_Quad_Output (default) hw:1 ft4
if you suspect jackdbus is messing with above settings, try for instance
to disable the d-bus interface from the qjackctl setup misc tab. that will
let you try with plain jackd (no dbus) after restarting qjackctl

So, here's what I've got going on that makes it all rather tricky.
- Sometimes I'm in my studio, with the m-audio. Sometimes I'm away, and need to switch to the built-in hardware.
- Most of the time I only need stereo output from the m-audio, but I do need to use quad occasionally.
- (I know I'm going to get a lecture about this) For regular, daily use, I can't do without pulseaudio. I have an RSI which forces me to do most of my prose writing using dictation software -- NaturallySpeaking running in VirtualBox. It's an absolute necessity -- can't get by without it. VirtualBox only supports pulseaudio, and for voice dictation, obviously I need to get audio input into the virtual machine. So it's not an option to uninstall pulse.
I have disabled pulseaudio's autospawn, and I can selectively turn on pulseaudio when I need it. Obviously, in critical performance situations, I would run jack only and leave pulse off. For daily use, it's extremely useful for me to have e-mail and the dictation software in one workspace, and SuperCollider in another workspace, so that I can write an e-mail quickly if I run into a problem.
In short, I know pulse is really wretched, but I would have to disregard advice to uninstall it.
- My typical configuration in 10.04 was to play back to the m-audio, and capture from the built-in hardware (headset microphone for dictation). Of course I wouldn't do that in a concert setting, but for daily use, in a development or composing cycle, that's what works best for me.
In short:
- Most of the time: -Chw:0 -Phw:1
** Edit: Actually, I think pulse will try to use the built-in hardware by default instead of the jack sink. So maybe this is not an issue. Let me try it and reply later.
- When I'm away from the studio: -dhw:0
- When I need quality mic input: -dhw:1
- When I need quad output: -Chw:1 -Pft4
So, if -C and -P are "contraindicated" as the doctors say, what's the best way to accomplish these? Only the last is a performance situation, so maybe I only need to worry about .asoundrc weirdness for that case.
Or, should I just keep doing things the way I have been doing them, and hack around the dbus problem until a proper fix comes (or I try kxstudio's ppa)?
