/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.

||||

|
||||
|
||||
|
||||
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/.
