via82xx + 4 cs4297 audio codec

via82xx + 4 cs4297 audio codec

[Carl Lee]

Hello Alsa-Community,

I have a custom audio card with the Via 8233
controller and 4 CS4297 codecs.  I want each of the 4
codecs to be a seperate "player."  So I want the
ability to play 4 different files at the same time,
one file per codec.  My question is does the alsa Via
8233 driver already support this or do I have to make
some code modifications?  Using alsa.rc6 (an older
library) I was able to play a file (using mpg123) on
the first codec no problem.  Any ideas on how to play
files on the remaining 3 codecs?  Is there some module
parameters I need to supply?  If I need to change the
code, no problem, I have to do it..please send me some
ideas and how long you think it would take for a
novice like myself.

Thanks in advance.

Re: [Alsa-user] HDSP + multiface + PCMCIA

[jfm3]

At this point in my limited understanding of it, you run hdsploader and
hope for the best. Let me know if running hdsploader works for you.

Good luck!

i'm afraid that it's difficult to do that with via8233 chip.
the multiple codecs are supposed to be used as a surround system.
you cannot specify the destination codec of each stream.
