Hello,
I have a PC with an ASUS M4A78-AM motherboard with integrated VT1708S
6-channel sound chip in it. However, I can't get the surround sound
working. The motherboard has 3 jacks on it - green for front / 2 speaker
set; blue is the line in or the rear-speaker out in 4.1 configuration, and
pink is the microphone or side speaker out in the 6-spk configuration.
My speaker configuration is 4.1 [2 front, 2 back and subwoofer]. Line in
does not produce any sound.
Speakers are connected properly. I have tried all possible configurations
of alsamixer and the rear speakers connected to either the blue or pink
jack, but it just doesn't work.
I have also tried many configurations in /etc/asound.conf or ~/.asoundrc.
In alsamixer, there is a control named "smart 5.1", turning it on or off
does not change anything. I have tried aplay to play some wav file using
-Dsurround40, but it does not work:
Playing raw data 'stdin' : Unsigned 8 bit, Rate 8000 Hz, Mono

I am using alsa 1.0.22.1. I have uninstalled and then reinstalled
pulseaudio sound server, so that it is not the default one and I get all
the controls in alsamixer (not just "volume" control). Surround sound did
not work out-of-the-box on fedora 12, and I never got it to work. Any help
would be greatly appreciated.
Best Regards
Viliam Kubis
