Re: Behavior of sndioctl

The commands run successfully but do not mute audio. This may be
because I'm listening from headphones and I have disabled laptop speaker
output through mixerctl outputs.master.slaves.

Interesting point. Relevant dmesg output:

azalia0 at pci0 dev 27 function 0 "Intel 82801I HD Audio" rev 0x03: msi
azalia0: codecs: Conexant CX20561
audio0 at azalia0

I'll continue to experiment and give an update if I find a solution.


Thanks,

James
