Starting and stopping Live TV inside MythTV multiple times will force it to come right but it means that recordings are hit or miss for sound quality. The only thing I have seen in this list that points to the hope of a fix is waiting for kernel 2.6.17...

Any progress on this? I spent this evening searching for a solution.
Everything works great if I use the tuner on the card, but I get the
tinny audio when using composite video/audio input. Not sure if it's
the same as what others have experienced. I have included links to
samples.

This output looks and sounds fine. Sample here: http://128.197.39.54/
foo.mpg
# But, now set video to composite input and line-in audio

This output has the tinny audio. Sample here: http://128.197.39.54/
foo4.mpg
Can anyone confirm this is the same type of audio distortion others
are experiencing?
My setup:
- WinTV PVR-150 (model 1045 -- if it makes a difference, this is NOT
the MCE edition)
- Fedora Core 5
- kernel 2.6.16-1.2111_FC5 #1 Thu May 4 21:16:58
- ivtv, version 0.6.2, release: 110.rhfc5.at
- ivtvctl, version 0.6.2 (development snapshot compiled on Mon May 8
07:30:56 2006)
Tinny audio with both firmware versions below:
- HcwMakoA.ROM (in /lib/modules linked as v4l-cx25840.fw in both /lib/
firmware and /lib/modules)
- HcwMakoC.ROM (in /lib/modules linked as v4l-cx25840.fw in both /lib/
firmware and /lib/modules)
Thanks to anyone that can provide some answers. It almost sounds
like the audio sampling rate is getting set incorrectly.
