Public bug reported:
(I'm attaching alsa-info.sh and I'm willing to try patches and/or
experiment with settings to get this fixed)
When I record sound in the gnome-sound-recorder the recorded audio comes
out of loud horribly crackling noise or sometimes as plain silence,
whenever I set "capture" volume to anything above 84 (I did a small
binary search to find out that 84 is the magic volume that works whereas
any volume higher than that does not work). I've test this very
carefully and I'm absolutely sure that changing _only_ the capture
volume (not changing any other setting) introduces the crackling noise
and lowering the capture volume again makes it to away.
I've confirmed this in detail with gnome-system-recorder because I
wanted to make sure the bug was still there with a very simple
application (what really prompted me to start investing with was that
skype didn't work, it suffers from the exact same problem).
In general this is an old machine which has been upgraded to jaunty
recently.
