ALSA trouble [SOLVED]

Ok, here's another "weird" problem from me
I installed Arch 2 days ago and ALSA wasn't working in the first place (e.g. two apps weren't able to play the sound at the same time). After "alsaconfig", everything worked like charm. Unfortunetely, i had to reinstall arch. I repeated the whole action this time too, but now it doesn't work . How is that possible?
(i read through wiki, and all similar topics in the archive, but nothing worked)

thx in advance

Re: ALSA trouble [SOLVED]

What is broken ? Simultaneous playback by two apps or no audio output at all ?

Re: ALSA trouble [SOLVED]

What kind of hardware do you have, and which modules are you loading?

Re: ALSA trouble [SOLVED]

MODULES=(forcedeth slhc ac97_bus snd-mixer-oss snd-pcm-oss snd-page-alloc snd-pcm snd-timer snd snd-ac97-codec snd-intel8x0 soundcore)

and the soundcard is: nVidia Corporation CK804 AC'97 Audio Controller

i mean, the thing that confuses me is that it worked before the reinstall, and after repeating the exact same procedure now, it makes problems

Re: ALSA trouble [SOLVED]

Are the two different applications using ALSA ? Maybe one is configured to use OSS ....
What happens when you run two instances of mplayer as : "mplayer <file_name> -ao alsa" ?

Also, take a look at the dmix plugin - http://alsa.opensrc.org/index.php?title=DmixPlugin

Re: ALSA trouble [SOLVED]

here are my results:
two "-ao alsa" mplayers - both work at the same time
exaile + mplayer - only one works
d4x (introductory music) + mplayer - again, only one works (note: d4x depends on alsa-lib )

wiki says that newer alsa versions have gmix included

Re: ALSA trouble [SOLVED]

I just checked and exaile and mplayer were not able to play simultaneously.
I think this was because exaile was using an non-alsa sink by default.
Installing 'gstreamer0.10-alsa' and choosing 'alsasink' in exaile's preferences fixed the issue.
