Again, mplayer has problems, mpg123 works. This time mplayer started
playing video (w/o sound) after long delay.

Uh. huh. And now problems appeared in mpg123, too, and then went away
in mpg123 _and_ mplayer. Interesting.

I suspect some pulseaudio fun. chromium always has sound problems,
then I restart chromium and everything is ok. But something changed in
-next and 4.15-rc1, because mplayer did not have problems before.
