Recently (Dec. 11) I posted the following:

The only response came from Mark Boyns ( who said:

Mark> About your /dev/audio busy, are you sure the volume is not 0?

After more discussions with Mark and some trial & error, I have the verdict:
The culprit is the existing audio code of Lucid Emacs 19.3.

Jamie Zawinski ( has sent me a new version of the audio code
that no longer hogs the audio device. It works fine on my SunOS 4.1.3, but
your mileage may vary...
