If I disable audio, shouldn't the Radeon HDMI ALSA device disappear? That
didn't happen for me when I set radeon.audio=0. Am I doing something wrong?

Could it be a timing issue? Audio init delays startup enough that it doesn't
hit some races anymore?

A broken system sometimes managed to recover after coming back from suspend,
though rarely.
