Hmmmm... on-board audio works fine for me using ALSA. I did initially
have a problem with btaudio for one of my capture cards grabbing dsp0
before ALSA loaded. I fixed that by adding: "post-install snd-intel8x0
modprobe snd-pcm-oss" to modules.conf.

I also have a noticeable glitch during channel changes. I think this is
Myth-related and has been discussed before. Someone suggested having
Myth auto-dampen sound during a channel change. Not sure if that would
fix it or not...

I'm successfully using the 4191 version of the drivers. I downloaded the
source RPM and rebuilt it for my kernel.

I have done a little bit of Googling for this, but was unable to locate
any for sale.

Good luck,
