[mythtv-users] No audio with PVR-250

[Paul Peltz, Jr.]

When I upgraded to mythtv-0.11 on my gentoo system my myth system
stopped recording audio with the video, and I just noticed a few days
ago and have been trying to diagnose the problem.  I searched through
the archives and couldn't find anything similar to my problem so I'll
try here.  I'm using a Hauppauge PVR-250 and the correct msp3400.o
module is loaded according to the documentation.  I've just downloaded
the latest ivtv version from cvs and compiled it, so I don't think it is
an ivtv problem, especially since it used to work.  This is the output
from dmesg when I do a recording:

i2c-core.o: i2c core module version 2.7.0 (20021208)

Nothing appears to complain when it is recording.

I'm sure there is more information that I am forgetting, so if you have
questions please ask.  I'll provide whatever is required.  Thanks for
helping me out.
