	after using zzz to suspend or sleep the sony vaio z505LS, it's
	yamaha audio chip produces nothing but high pitched buzzing while
	trying to use xmms 1.2.4 or mpg123 to play mp3s.  restarting the
	application has no effect.  reboot fixes it.

	the chip is reported as
	yds0 at pci0 dev 9 function 0: Yamaha 744 (DS-1S) Audio (rev. 0x02)
	yds0: interrupting at irq 9
	yds0: Asahi Kasei AK4543 codec; headphone, 18 bit DAC, 18 bit ADC, AZTECH 3D
	audio0 at yds0: full duplex, mmap, independent
	opl0 at yds0: model OPL3
	midi1 at opl0: DS-1 integrated Yamaha OPL3
	mpu0 at yds0
	midi2 at mpu0: Yamaha DS-1 MIDI UART

	suspend or sleep the laptop, revive, and try to play an mp3.
	unknown.  i know very little about pc h/w, but willing to take
	pointers to help solve the problem.
