Fix bug uncovered by audio.c fix: Since the monitor control on the ESS
...
is a muting control, not a level control, change the name to reflect that.
XXX The fact that the audio code depends on the string names of the
XXX mixer devices is bogus.

Fix a couple of other places we should avoid the Audio2 DRQ on the 1788.

More redux:
...
* Use a single routine to halt both input and output on Audio1.
* Reduce the number of register reads/writes used to set up a channel.
* A few other minor things.

Minor fix to some debugging output.

3e404912dc
Clean up the previous:
...
* Separate the interrupt handlers based on which channel (audio1/audio2)
rather than which direction (input/output). Only register the handler for
audio1 on the 1788.
* Since the input sides are actually the same, GC the duplicated code.
* Re-KNF in a bunch of places.
* Make this work again on the 1887 in the Shark.

* Redo the way the way the MIDI driver attaches to audio devices.
...
* Improve the midisyn layer a little.
* Add a driver for the Yamaha OPL[23] FM synths.
The opl driver is not finished yet; it sounds pretty awful.
For some strange reason I cannot get any FM sound from my SB64 cards,
but a regular SB16 works fine.
