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?

Double-checking my PVR 350 configuration, you need to set your audio input to Tuner 1.
