Hi, there
I have a box with cmedia 8738-mc6 pci card. I can get only stereo
playback with it, while the card is supporting 5.1 channels. Works fine
on linux using mplayer -channels 6 ...
I've appied the patch from http://people.freebsd.org/~ariff/
I can get the new sampling rates working. Is there any chance I can get
this card running in multichannel 5.1 mode ?
Regards,
Todor
