Apologies. I read no sound and ALC256 and my tired brain
did s/speaker/microphone/g because I have two machines affected by the
same and the question came up from other people fairly often...
Maybe a stupid idea, but is you speaker muted via hardware and it's not
reflected in sndioctl? I have one laptop where the hardware and software
mute states are independent. (or rather not correctly synchronized on
OpenBSD)
Nice Laptop btw. I had forgotten about tuxedo.
