I'm using running MythTV with a Hauppauge PVR-350 on Ubuntu Linux. After
upgrading to Hardy Heron
(kernel 2.6.24-16, ivtv 1.1.0, mythtv 0.21.0), there's no longer any sound in
my recordings, nor is
there sound when watching live tv. I've confirmed that the audio line into the
PVR-350 is still
good and has sound.
When I do "cat /dev/video0 > test.mpg", the video is fine, but there's no sound
in test.mpg, even
when played on another known working computer. When playing recordings from
before the upgrade, the
sound is there like normal.
Here are some configuration settings:
# v4l2-ctl --list-audio-input
ioctl: VIDIOC_ENUMAUDIO
Input : 0
Name : Tuner 1
Input : 1
Name : Line In 1
Input : 2
Name : Line In 2
# v4l2-ctl --get-audio-input
Audio input : 1 (Line In 1)
Below is the ivtv output from dmesg. Does anyone know what's wrong? What
other logs or
configuration settings can I look at to troubleshoot the problem?
Thanks for your help!
