[mythtv-users] Anyone have a CX8800-based capture card working in MythTV?

Don,

Your post is a little confusing. You have to try to pinpoint *where*
the problem lies, whether it's in your capture card or your sound
card.

I'm using an Audigy with a BT878 framegrabber Kworld card with the
same exact motherboard as you. The only difference we have is the
capture card. It should be fairly trivial to figure out whether there
is audio out coming out of your capture card or not (ie. plug
headphones into the audio out and check). If there is audio out, then
you should hook the audio out of the card to the line in of the
Audigy. Then, configure alsamixer correctly (this is pretty tricky, I
can send you my settings if you'd like after you've confirmed that the
capture card audio is working).

Hope this helps,
andrew
