I have the same problem. Downgrading Audacity doesn't solve it for me.
I had same problem when used JACK and had following in .asoundrc: pcm.!default { type plug slave { pcm "jack" } } [...] A fix was to rename plug (!default -> plugjack or so), start audacity, configure audio-in and audio-out to JACK. After that I returned asoundrc to previous state, and audacity started without a problem. Although this was nearly 6 months ago, so I don't know can it help or not.
The message audacity: pcm_plug.c:388: snd_pcm_plug_change_channels: Assertion `snd_pcm_format_linear(slv->format)' failed. is not the cause of the crash, as this message is encountered even when Audacity is working. If this is still a problem in 1.3.12 (#312837), can reporters confirm that they are 1) using Jack 2) building Audacity with the jack use-flag 3) have set their .asoundrc to divert ALSA default output to Jack?
Sorry, no more on gentoo :-( impossible to redo the test. You can close the bug.
Well, I'm not on gentoo (ubuntu lucid, with audacity 1.3.12 from a ppa) but I can confirm that 1. I try to route stuff to jack via .asoundrc 2. audacity 1.3.12 still crashes: audacity: pcm_plug.c:388: snd_pcm_plug_change_channels: Assertion `snd_pcm_format_linear(slv->format)' failed.

Somehow I managed to kill jackd while running audacity in gdb. Might be concidence (I have some background computing going on, network transfer, ardour2 open) -- at least it is another sign that I probably never will get a stable setup with my firewire device. Even had to power cycle it to make it talk to jackd again. I wonder if someone reported this to audacity folks yet? Or rather portaudio?
Eh, wait... the assert fails in ALSA ... so it's a but in libasound? It should rather gracefully handle any question that audacity / portaudio pose.
I can confirm this on gentoo.

Yes. To get Audacity start, I had to start it without the default divert in .asoundrc (3). After that, I could configure Audacity and restore the .asoundrc. Here are some of the differences to audacity.cfg after that: -Version=1.3.7 +Version=1.3.12-beta [AudioIO] PlaybackDevice=JACK Audio Connection Kit: system -RecordingDevice=ALSA: Aureal Vortex au8820: adb (hw:1,0) +RecordingDevice=JACK Audio Connection Kit: JackMix +Host=JACK Audio Connection Kit If I delete the audacity.cfg I just fixed, I get back to the same "audacity: pcm_plug.c:388:" -assert error. Without the .asoundrc, audacity starts with message: Expression 'stream->capture.pcm' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 3653 That detects and saves the default config. Here is the diff to get back to working jack setup: [AudioIO] -RecordingDevice=ALSA: default +RecordingDevice=JACK Audio Connection Kit: JackMix -PlaybackDevice=ALSA: Intel ICH5: Intel ICH5 (hw:2,0) +PlaybackDevice=JACK Audio Connection Kit: system -Host=ALSA +Host=JACK Audio Connection Kit
I get the same error (in Gentoo) with Audacity versions 1.3.8 and 1.3.12. Audacity would die either immediately after the first-run "Select Language" screen, or immediately. Ubuntu users seem to also have reported this issue [1]. And as mentioned in the comments for this bug above, they related it to the issue with using "Jack". However, re-emerging Audacity without the "jack" USE flag did not help. The only thing that allows Audacity to run successfully (for me, at least) is to rename ~/.asoundrc (like: 'mv .asoundrc .asoundrc2') Then, after Audacity runs, I can rename that file back to its original name. Or, from within Audacity, I can go Edit->Preferences->Devices->Recording and then move the selection off of "Default." Now Audacity will run even with ~/.asoundrc I noticed that Comment #2 (from Simeon) looks helpful, but I don't have anything related to "jack" in my .asoundrc file. My hunch is that Audacity can't handle certain types of items in .asoundrc. I'll copy/paste my .asoundrc file [2]. [1] https://bugs.launchpad.net/ubuntu/+source/audacity/+bug/159671 [2] My .asoundrc file: # Taken from: http://www.thedigitalmachine.net/alsaequal.html ctl.equal { type equal; } pcm.plugequal { type equal; # Modify the line below if you don't # want to use sound card 0. slave.pcm "plughw:0,0"; } #pcm.equal { # Or if you want the equalizer to be your # default soundcard uncomment the following # line and comment the above line. pcm.!default { type plug; slave.pcm plugequal; }

I confirm the systematic occurrence of this problem with 1.3.12 1/ Using Jack And 2/ Building Audacity with the jack use-flag And 3/ Diverting ALSA default output to Jack via /etc/asound.conf Following my asound.conf : pcm.!default { type plug slave { pcm "jack" }} pcm.jackplug { type plug slave { pcm "jack" }} pcm.jack { type jack playback_ports { 0 alsa_pcm:playback_1 1 alsa_pcm:playback_2 } capture_ports { 0 alsa_pcm:capture_1 1 alsa_pcm:capture_2}}
Is this still an issue in 1.3.13?
Audacity-1.3-14 will be removed ASAP, can you reproduce this bug with latest stable 2.0.0?
No response since 2011-08-23 after Tim comment, close for now.
