Yeah, I figured it out (was in a hurry three hours ago).
It'll be huge change to revert to plain alsa.
In the meantime I capture separately, video with mencoder, with the
lines I gave, only modified, added nosound=1 in the profile, and
separately sound with ffmpeg, and later cut and join the two streams.
It's much more work, but I don't lose the quality at all. I get all
the card gets.
They described pulse as having fine future, but it doesn't seem to be
the case, does it?
I understand that it is no good for capturing with ffmpeg at this time.
But it seems additional work to revert to plain alsa,
So if I could get the mencoder to somehow capture sound as well, I'd
stay with pulseaudio.
So I think I'll go and ask about this issue on pulseaudio mailing list
If a solution isn't offered there, reverting to plain alsa seems the
right way to go.
