/proc/sound, /dev/sndstat
-------------------------
/proc/sound and /dev/sndstat is not supported by the
driver. To find out whether the driver succeeded loading,
check the kernel log (dmesg).
ALaw/uLaw sample formats
------------------------
This driver does not support the ALaw/uLaw sample formats.
ALaw is the default mode when opening a sound device
using OSS/Free. The reason for the lack of support is
that the hardware does not support these formats, and adding
conversion routines to the kernel would lead to very ugly
code in the presence of the mmap interface to the driver.
And since xquake uses mmap, mmap is considered important :-)
and no sane application uses ALaw/uLaw these days anyway.
In short, playing a Sun .au file as follows:
cat my_file.au > /dev/dsp
does not work. Instead, you may use the play script from
Chris Bagwell's sox-12.14 package (available from the URL
below) to play many different audio file formats.
The script automatically determines the audio format
and does do audio conversions if necessary.
http://home.sprynet.com/sprynet/cbagwell/projects.html
Blocking vs. nonblocking IO
---------------------------
Unlike OSS/Free this driver honours the O_NONBLOCK file flag
not only during open, but also during read and write.
This is an effort to make the sound driver interface more
regular. Timidity has problems with this; a patch
is available from http://www.ife.ee.ethz.ch/~sailer/linux/pciaudio.html.
(Timidity patched will also run on OSS/Free).
MIDI UART
---------
The driver supports a simple MIDI UART interface, with
no ioctl's supported.
MIDI synthesizer
----------------
This soundcard does not have any hardware MIDI synthesizer;
MIDI synthesis has to be done in software. To allow this
the driver/soundcard supports two PCM (/dev/dsp) interfaces.
There is a freely available software package that allows
MIDI file playback on this soundcard called Timidity.
See http://www.cgs.fi/~tt/timidity/.

* Here is how the values are used for reading.
* The value 'active' simply indicates the DMA is running. This is done
* so the driver semantics are DMA starts when the first read is posted.
* The value 'front' indicates the buffer we should next send to the user.
* The value 'rear' indicates the buffer the DMA is currently filling.
* When 'front' == 'rear' the buffer "ring" is empty (we always have an
* empty available). The 'rear_size' is used to track partial offsets
* into the buffer we are currently returning to the user.
* This level (> [1.5]) doesn't care what strategy the LL driver uses with
* DMA on over-run. It can leave it running (and keep active == 1) or it
* can kill it and set active == 0 in which case this routine will spot
* it and restart the DMA.
