Hmm... when trying some flac files I get this error
ALSA lib pcm_dmix.c:996
snd_pcm_dmix_open) unable to open slaveDon't know why yet...but I'll keep on googling
And Im now up to Rev 13986.

Can you try to rebuild with USE=debug and repost your backtrace? Also, make sure the file /usr/local/share/xbmc/system/players/paplayer/MADCodec-i486-linux.so exists.
- alphacube - 2008-07-09
Thnx althekiller for taking a look.
Here's the backtrace
And the debug log again
And yes MADCodec-i486-linux.so exists in
/usr/share/xbmc/system/players/paplayer/MADCodec-i486-linux.so

Here's a link to the strace log
Enjoy

Hmm, seems the ebuild doesn't handle the debug flag properly. Any chance you can grab sources and compile yourself?

np give me an hour

hmm... when you say it I think I used the xbmc bin which is just a bash script that runs /usr/share/xbmc/xbmc.bin -q
will try the xbmc.bin directly
- alphacube - 2008-07-09
here's the full output of gdb when I run /path/to /xbmc.bin directly and I see the debug info on the top
gdb bt
and why not yet another logfile

Ok this is what makes things intressting. ^^
I downloaded it again as a regular user run build.sh enabled debug in settings -> System
played an mp3 file and got "ALSA lib pcm_dmix.c:996: (snd_pcm_dmix_open) unable to open slave"
well it does'nt segfault anymore
and I used the same rev as my system wide installation
The logfile
any clues someone...

You either have a bad ~/.asoundrc file or something has a lock on your output device.
- alphacube - 2008-07-09
tought so too...but movies play fine and using external app works fine....even the klick sound when walking trough the menus work fine...
Well, I'l poke around little more

I'd go with what Al said, pretty sure it's a bad .asoundrc file. See my post here
