Description of problem:
My "Pinnacle PCTV USB2 PAL" device provides a /dev/video2 and a pulseaudio/alsa_input.hw_1 device. The video looks good, but the audio stream sounds really bad... example: http://www.wgboome.de./bla.wav

On linux-media mailing list someone suggested, that the usbaudio driver gets some YUV data mixed with audio data...

I think even with a filter that removes extreme values
(http://www.wgboome.de./blah.raw -> http://www.wgboome.de./blah.ogg)
the device will be unusable,
because: the sample rate is unknown...

Version-Release number of selected component (if applicable):
fedora core 14
fully updated

How reproducible:
always

Steps to Reproduce:
1. plug in the device
2. mplayer -tv 
driver=v4l2:input=0:width=768:height=576:device=/dev/video2:norm=5:chanlist=europe-west:freq=224.25 tv://
3. parec --device=alsa_input.hw_1 > bla.raw
  
Actual results:
loud noise + good video + (shifted?) sound

Expected results:
good video + matching sound

Additional info:
the ms windows drivers deliver bad sound 2, i have been told...
