augustss 0db08d11e6 Redo the SB mixer code. The driver can now distinguish between the
four different mixer options: none, CT1335, CT1345, and CT1745.
It should now be possible to access most of the SB16 functionality.

augustss 8d6f509439 Mask the level registers as the documentation suggests. 1997-05-18 00:36:03 +00:00
augustss d7a82223f4 Change lowater calculation a little.
Fix mixer setting bug and add some missing splaudio().
Set SB drq16 to 5 and don't pretend to be SB v1.0.
1997-05-17 23:26:33 +00:00
augustss abdd4ddbea Back to pretending to be a SB v1.0 again, the mixer code for higher
versions is buggy.

augustss 37be371415 Clean up emulation code, SB, and GUS drivers and add some more encoding
emulation to SB.

augustss e63a553175 Change the interface between high and lowlevel audio drivers again:
Set the encoding parameters slightly differently.
Remove the SW encoding/decodinf functions from this interface
and move them to the audio_parameter struct; this is both more efficient
and flexible.
1997-05-09 22:16:27 +00:00
augustss c4a52794f1 Convert to new orthogonal audio encoding scheme and implement
some of the new encodings.  The change to ioctl AUDIO_GETENC is
NOT backwards compatible.

augustss 2fb1d088c5 XXX Pretend that all SB cards are of model 1.
XXX This way you can at least use SB cards until the real fixes go in.
1997-04-30 02:08:12 +00:00
augustss 526ef2f618 Change the interface between the high and low level audio drivers
so that all audio encoding parameters are set at once.  This simplifies
the interface and make error checking easier.

mycroft 4f9648674a Make sure we round the block size to a multiple of the sample size. 1997-03-20 20:15:24 +00:00
mycroft e0b3534b6c Remove bogus block rounding code. If the application sets a
block size explicitly, it had better know what it's doing.  From

jtk 8b3873367f add MediaVision Jazz16 chipset support. It must be configured with
'flags 1' on the sb? kernel configuration file line (because it frobs a
noncontiguous IO port to configure the Jazz16 extensions).

Also, remove static sb_device structure and fill in user's buffer on
each request.

mycroft 7847c9efee Various:
* Snap the sample rate when setting it, and remember only the time constant.
* Set the time constant when changing between play/record.
* Always return the actual sample rate with AUDIO_GETINFO.

mycroft 7af4edd731 Various, including:
* Add more delays while writing registers.
* Replace sc_dma{in,out}_inprogress with sc_dmadir.
* Eliminate the need for sc_locked.
* Add more DPRINTF()s.
