Here is an email I stumbled across: ---] Jim, I guess I never saw your email. I also have an AverTV Stereo card which i bought from CompUSA. The problem with the card is that the bttv driver doesn't know the card. I even downloaded the latest version from http://www.bytesex.org/bttv and no success on autodetection. When I look at dmesg the card gets autodetected as card 13 and everything works except for the audio being the SAP channel. I didn't find any solutions anywhere but finally figured out that the audiomux settings for the autodetected card were to blame. Using bttools in Windows with the drivers installed I figured out that the correct setting to get stereo sound is 0xff44e. So: modprobe bttv audiomux=0xff44e For some reason it didn't seem to work from modules.autoload so I had to manually rmmod and modprobe every time. That gave me problems when I got the second card though because when you modprobe bttv it detects both cards and the other card didn't like the audiomux setting. My solution was to go to the bttv source (bttv-cards.c), change the first value in the audiomux array to 0xff44e, make, make install and modprobe bttv. Now everything works just fine without having to put any arguments on bttv. -Emil ---] I have recompiled the driver with the change to the audiomux and it seems to work for me. However, I am not sure what you mean by "digital" sound. I have been using the card with MythTV. Hope it helps. ---Dan On Fri, Apr 11, 2003 at 07:28:53PM +0200, avilella wrote: > Dears, > > I'm trying to get the sound working in my Avermedia AVerTV with the > msp34xx Stereo Nicam chip. > > Since I bought it I haven't been able to get the sound working.
