enabled as default for soundcards which don't support hw mixing."
I've found this to be the case on my laptop, where I use:
export QEMU_AUDIO_DRV=alsa
export QEMU_AUDIO_DAC_FIXED_FREQ=48000
export QEMU_AUDIO_ADC_FIXED_FREQ=48000
export QEMU_ALSA_DAC_BUFFER_SIZE=16384
Buffer size is very important, else it crackles and pops for me.
Now if only sound could survive a loadvm/savevm it'd be perfect. :-)
