|
* Maestro-3/Allegro FreeBSD pcm sound driver
|
|
*
|
|
* executive status summary:
|
|
* (+) /dev/dsp multiple concurrent play channels.
|
|
* (+) /dev/dsp config (speed, mono/stereo, 8/16 bit).
|
|
* (+) /dev/mixer sets left/right volumes.
|
|
* (+) /dev/dsp recording works. Tested successfully with the cdrom channel
|
|
* (+) apm suspend/resume works, and works properly!.
|
|
* (-) hardware volme controls don't work =-(
|
|
* (-) setblocksize() does nothing.
|
|
*
|
|
* The real credit goes to:
|
|
*
|
|
* Zach Brown for his Linux driver core and helpful technical comments.
|
|
* <zab@zabbo.net>, http://www.zabbo.net/maestro3
|
|
*
|
|
* Cameron Grant created the pcm framework used here nearly verbatim.
|
|
* <cg@freebsd.org>, http://people.freebsd.org/~cg/template.c
|
|
*
|
|
* Taku YAMAMOTO for his Maestro-1/2 FreeBSD driver and sanity reference.
|
|
* <taku@cent.saitama-u.ac.jp>
|
|
*
|
|
* ESS docs explained a few magic registers and numbers.
