[mythtv-users] WinTV PVR 250 Audio

I've been wrestling with this one for hours:
After fiddling and fiddling and fiddling, trying to get around the fact
that I can't get an image if mythbackend starts before the X session, I
realized that I suddenly no longer had any audio.
Of course, I did double-check, and previous recordings do play both
video and audio, but new ones do not.
Nor does mplayer /dev/video0 play audio, either, and manual recordings
with the perl script provided with ivtv also have no sound.
I've set the debugging to 2 on the msp34xx, and I find these messages:
msp34xx: switching to TV mode
msp34xx: MSP_SET_MATRIX
msp34xx: scart switch: mute => 1
msp34xx: MSP_SET_MATRIX
msp34xx: scart switch: mono => 1
I've experimented with lowering and raising the bitrate using
test_ioctl, but to no avail.
I am most definitely using the ivtv-specific version of the msp3400
module, with MythTV .10 on a Mandrake kernel 2.4.21-0.18mm.
This is particularly frustrating, as I seemed to have it all set until a
few hours ago.
I believe I've got Alsa configured correctly, with Line-in muted and set
as a recording source, too.
Has anyone else encountered and defeated this situation?
