I'm using alsa for years now and it has always been fine; especially it
has always been possible without any problems to have multiple apps
running that access the sound card. For example i could start audacious
to play some music and to totem and watch a movie _with_ sound; or play
some music and start a game etc. Yesterday, i noticed, that this is
no longer possible: For example, if i try to play a mp3 in gmplayer
while running audacious i get:
alsa-init: using device default
alsa-lib: pcm_dmix.c:914:(snd_pcm_dmix_open) unable to open slave
alsa-init: playback open error: Invalid argument
Could not open/initialize audio device - no sound.
Now the funny thing is, that the same works as root; so i guess that
some permissions are not set correctly (note that my everyday user is in
the audio group) and perhaps, but this is only one possible explanation,
this is because i've upgraded to sys-fs/udev-103 recently ...
any ideas ?
btw, this is my sound-card: Creative Labs SB Live! EMU10k1
