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.


# First, set video and audio to PVR-150 tuner, and set tuner to  
channel 3 (since I have a digital cable box connected)
 > ivtvctl -p0
 > ivtvctl -q0
 > ivtvctl -r 980
 > cat /dev/video0 > foo.mpg    # ctrl+c to stop capture
 > mplayer -vo xv foo.mpg

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
 > ivtvctl -p2
 > ivtvctl -q1
 > cat /dev/video0 > foo4.mpg   # ctrl+c to stop capture
 > mplayer -vo xv foo.mpg

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.
