[Alsa-user] Games Theatre XP 6.1 and surround

[Johan G. <jg...@ds...>]

Hi everybody,
I wonder what the status of the cs46xx driver is concerning 5.1 surround
with analog speakers? AC3 hardware passthrough seems to work well at the
moment :). I'm using mplayer to play dvds.

I've tried:

$ mplayer -aid 128 -dvd 3 -vop pp=0x20000  -ao alsa9:surround51 -channels 6

but as you can see no luck. Is it possible to get 5.1 sound with GTXP
6.1 with alsa9 (cvs-version) and latest mplayer.

Cheers,
Johan
