audacity crashes on startup

[bea]

Hi folks,

i am havin problems to start audacity for a while.

Meanwhile I am running a recently updated installation of sabayon; audacity is 2.0.

Problem:

ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear
ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.center_lfe
ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.side
ALSA lib pcm_dmix.c:957:(snd_pcm_dmix_open) The dmix plugin supports only playback stream
Expression 'stream->capture.pcm' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 3857
audacity: mask_inline.h:160: snd_mask_leave: Assertion `val <= 64' failed.
Aborted

Currently the machine is running Jack. There are two soundcards:
504> cat /proc/asound/cards
0 [tm ]: USB-Audio - Audiophile USB (tm)
M-Audio Audiophile USB (tm) at usb-0000:00:1a.0-1.1, full speed

card 1 is not used. apparently, audacity tries to access the internal card. Sound is working, at least playback from ogg123, vlc and firefox.
I have set up pulseaudio to work through jack, but the problem existed when the machine was running pulseaudio in its default configuration.

Google tells me that problems of this kind are not uncommon.

Any ideas?
