FM801 5.1 surround

FM801 5.1 surround

[Emilio Federici]

Hi everybody! I was wondering why my Abit AU10 FM801 isn't able to play through central channel.
Actually by turning on the 'Surrond' amixer control I was able to hear the two rear channels but no luck with central one.
Is it still unimplemented and if so is it possible/easy to do it myself?

Thanks in advence for ur help.

which ac97 chip on the card?  no relevant mixer elements?

i guess the fm801 engine itself already supports 6 channels but the
codec is not.

Hi Takashi, thanks for your immediate answer. I unplugged the card and found it has 2 ac97 chips:

SIGMATEL STAC9721T
WM XWM9704

This is the 'amixer scontrols' output:
[root@localhost root]# amixer scontrols

Simple mixer control 'Master Mono',0
Simple mixer control 'Master',1
Simple mixer control 'Master Mono',1
Simple mixer control '3D Control - Center',0

I'm considering upgrading to a Sounblaster Audigy (for this among many other reasons) but I read that it has similar problems with 5.1 output, is that still true?

Thanks for your help
Bye!

as you see above, there are double entries with different indices, so
apparently the fm801 driver already probed two codec properly.

i guess you didn't configure the secondary codec.
please try unmute and adjust the volume of secondary mixer elements,
i.e. 'Master,1' and 'PCM,1'.
most likely this corresponds to the center/lfe volume.

iirc, it works for analog outputs.
the digital output seems not working yet.
recently a patch was applied to support the spdif i/o on audigy drive,
but i myself cannot test it.
