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...
