Re: freebsd hdmi audi

Which specific CPUs are producing sound on hdmi port?  Are you running 
an external monitor on the dell laptop?

My systems contain; i3-7100 (Kaby Lake), i7-8700 (Coffee Lake), i7-10700 
(Comet Lake).

I suspect that with each CPU variation, Intel moved control 
registers/bits around.

I'm using i915kms.ko and hdasnd.ko (I believe).  I can spin up a machine 
and do kldstat...
