Sorry, I forgot to mention that RealAudio player complains that it
"cannot open the audio device. Another application may be using it."

However, I just tried mplayer, which *does* work normally and the
master channel also works properly again.

So it seems that hp_only works, but only partly.  Any idea why
RealPlayer is complaining?

Most of that info means nothing to me, so all I can do is point you
the results, sorry:
