Scott Long ea0e6ecfe9 Don't re-init the mixer on resume. This keeps the channel volumes from 
being trashed when you suspend, though this may need to be revisited if we
ever get suspend-to-disk implememted.

/*
* 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.
