[mythtv-users] Does anyone using Knoppmyth R5A16 have a working BT848 card?

[Mark]

I have two PVR250's and one Wintv401 BT848 card in my system, but the 
audio isn't
working on the BT card.  I've tried everything I can think of.  My 
linein-lineout cable is
correctly installed, and I can get audio passthru by unmuting the SBLive 
Line-in.
If I mute it as you're supposed to, I get no audio.  It appears that 
myth isn't recording the audio.
And yes, I 've correctly configured /dev/dsp0 as the input on that 
card.  but it just doesn't
record anything.  Any ideas?
