Ok ppl hello.
I am trying for hours and hours to make my build in soundcard (Multimedia audio controller: VIA Technologies, Inc. VT8233/A/8235/8237 AC97 Audio Controller (rev 60)) to work in 5.1 mode and be able to control rear center and front speaker seperately. I ve done this with this config
pcm.!default {
type plug
slave.pcm "softvol"
pcm.softvol {
type softvol
slave.pcm "ch51dup"

I can also play Quake3 and listen to music in the same time. But i cannot use skype and it seems i cannot have any input from mic.
I need to have mpd working also.
I tried to use jack but no luck.
Any ideas ??????

Answer 1

hi man,
i have created a ~/.asoundrc with this line
pcm.!default {
type plug
slave.pcm "surround51"
slave.channels 6
route_policy duplicate
and i thinik it works, except a problem in kde
Sound server informational message:
Error while initializing the sound driver:
Unable to set interleaved!
The sound server will continue, using the null output device.
but i think is that kde don't know to use the file created and make errors at startx.
after this, my real problem is with the 3 plug line-out.
i have an onboard audio card with 3 plug: line-in line-out and mic.
as i have cabled the 3 line-out of my audio5.1 kit i listen sound only with sub and 3 speaker, i don't listen sound by the 2 rear speaker right and left because i think their respective plug that exit by the sub is on the mic or line-in plug on my mobo.
probably i don't have switched the plugs, what do u think?
i don't have changed anything except the creation of the asoundrc file.
finally: it could be nice managing the speaker separately front and rear.
overrighting my asoundrc with yours i will enable to do this?
edit: onboard i have an audio ac97 interface for the frontal panel with an aud-out and a mic.
don't u know how to use this frontal interfaces?
from me, actually the aud-out works and mic seems not work so good. is unuseless now the mic of the frontal panel.
