Does nforce sound with surround works?

tscolari

Ive a nforce4 motherboard that comes with the nforce sound (AC97 Compilant) its suposed to be a 7.1 sound system, but since it does not even play 2 sounds at the same time by hardware in linux Im a little afraid that these 7.1 channels doesnt even work too...
Have someone tested it? Im thinking about buying some sound boxes but before i need to know if it will work...
If it does are there any howto i could follow?

In case it doesnt, does that sound blaster live 24bits (7.1 i think) have these features on linux? (hardware mixing,surroun, ...)?

Not that familar with the Nvidia onboard sound, but if it's anything like a lot of onboard components, it's probably software driven 7.1 surround. The soundblaster 24 bit has hardware surround sound. It probably has a digital passthrough as well so you can connect it to a receiver. The sound blasters are supported pretty well with Alsa. I have a Audigy and it works fine. The passthrough works with my receiver, and I also have a set of Logitech 5.1 speakers that work great also.

Its a 7.1 onboard sound device, but i use the nforce driver (AC97) that was the same when i was using a nforce2 board (5.1) and so on... thats why im not too sure if it will work...

Im with the 5.1 sound kit here but im not getting it to work... I dont get sound in the center or rear... dont know what else i could change to make it work...
in alsamixer center is unmutted and on.

What should i configure?

Hei

In alsamixer make sure iec958 is unmuted and iec958p is at absolute zero..

Mvh

very strange...
this IEC958 and IEC958p doesnt seem to make diference in the output.
Im with a little surround here:

for example ive:
FRONT L
FRONT R
SUB
CENTER
REAR L
REAR R

I hear sound in the:
FRONT L
FRONT R
SUB
REAR L

do sound from center or the rear right...
any idea why this?

ive tested this in windows and all boxes are working ok there

Sorry, I was thinking of your using spdif 5:1 sound..
If you list the output of your sound device from lspci it might help others provide help

Not a lot on google other than info about intel-8x0.. are using a recent kernel?
And what versions of alsa are you using?
