audiomux=0xff44e should be correct however this didn't work for me.
The audio was ok but kept getting lockups with buffer overflow errors.
This is what is currently working for me audiomux=0x56664e.
However i don't think the sound is in stereo are it at least doesn't
sound as good as my other card (wintv 401).
