thanx, that helped.

You are right, Jindrich, it's no use to duplicate the functionality of
these tools. I never wanted to do that, I just did not know that they can
be used to set the recording source, cause I did not look carefully
enough (although I studied the aumix manpage). Therefore, I think it would
be useful to include somewhere in the mplayer documentation an example of
how to set the recording source using aumix/alsamixer.

Consequently, please don't apply the rest of the patch.

What do you think about the documentation patch at the end?
