If you do, then you can tell me if you get the same Segmentation fault error that I'm currently getting when recording a second track with Overdub enabled using ALSA for playback.
Audacity is working sweetly with Jack, but I'm having major problems with PulseAudio and ALSA.

steve, which wxwidgets version do you recommend? Should the 2.8.10.1 be fine?

I'm using 2.8.11.0 from the Ubuntu repository.
I think 2.8.10 should also be fine.

I just compiled the svn version (with wxwidgets 2.8.10.1 from debian's rep.).
I see no different behaviour from 1.3.12-beta in debian's rep.
Regarding my problem it still fails to start when it can't find the playing/recording devices.
BTW, can you help me testing this one too? Please edit your ~/.audacity-data/audacity.cfg file and look for these lines:
Code: Select all
[AudioIO]
PlaybackDevice=JACK Audio Connection Kit: system
RecordingDevice=JACK Audio Connection Kit: system
Change it to:
Code: Select all
[AudioIO]
PlaybackDevice=
RecordingDevice=
Start audacity... Does it start? Or does it crash?
Regarding your problem, it crashes when I select ALSA: default for playback, but that also happens with 1.3.12-beta (with jackd running in both cases and with jackplug configured in asoundrc to handle default pcm playback, if that matters...).

I was just thinking about my last post... and it might contain the answer to my problem...
While testing ALSA on your request I found that audacity crashes when selecting ALSA: default, so what probably is happening is that when it fails to open the device in the config file it will probably default to "ALSA: default" and that causes it to crash...
Edit: just to add that the reason why it crashes on "ALSA: default" is probably due to my .asoundrc config which redirects alsa's pcm to jack through jackplug... At least this is my most recent guess about it...
