a6a09bcdd6 Add support for ES18[67][89]. From PR #7427 by AW9K-NNK@asahi-net.or.jp, 
Nonaka Kimihiro.

70e38aa504 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.

b6ee330d4e dmapos should start at 0, in theory. 
Also experimentally force polling mode.

ff4754d6e5 Confirm that there was an interrupt before handling it. Allows IRQs to be

8ace2247cb Fix a couple of other places we should avoid the Audio2 DRQ on the 1788. 1999-03-17 02:39:59 +00:00

81a1ade358 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.

84f100d175 Audio1 does not support 16-bit DMA. Eliminate some code that tried to handle 
that case.

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.

64fffdfef9 Add support for the 1788 AudioDrive chip. 
Some minor cleanup; refer to more registers by macros rather
than raw hex constants.

ea50d6f672 Use DMAMODE_LOOPDEMAND.

packets on the Shark.

b81ad0de61 Fix the halt_input and halt_output routines to actually disable the channel, 
not just the DMA FIFO.  Fixes problems with sample misalignment.

e5f5e628d2 Pass the direction to the allocm and round_buffersize methods. 
Some drivers need this to properly allocate DMAable memory.

bb3c56652c Make the OPL driver turn on the sound on sound cards that require it. 
That makes it much more likely that we get any sound.  DUH!

cd09067eb4 * 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.

5c76b6a944 The mic preamp is really a property of the input stage, and affects both

0611fc34f8 Don't actually touch the hardware in set_params; defer that until we actually 
start a transfer.  Instead, just check that the parameters are valid.
Also, use 16-bit output for u-law and a-law.

080dc567e8 A first stab at an ESS1887 driver. The code is from the SHARK port 
and needs a lot of polishing.  The code compiles (on i386), but is
untested.  See ess.c for a TODO list.
