Confused audio channel output on hda-intel based device


Hi All,

I use ubuntu lucid x86_64 with pulseaudio.
There seems to be some issues with how the audio is sent to the sockets.
When playing an MKV with surround sound "front" recieves none of the actors voices. it almost sounds like it is the rear sound. Centre/subwoofer sound works correctly. I also get a problem with headphones and front where I cannot mute front and allow only headphones instead I can just mute headphone socket. This is entirely confusing so I hope someone can help me in the right direction.

Hardware:
Nvidia 7600 gfx
P5QL-EM mobo with 8 channel surround sound audio and hdaudio/ac97 cable which is set to hdaudio on mine in both bios and physically connected cable.

Some basic things I would first try:

1) Make sure the cables are plugged into the right ports, and plugged in well.
2) Extract the audio channels from the mkv and make sure that they were encoded properly, and that in fact there are voices that should be played on the front speakers.
