William, Thanks.
If your suggestion is that the speaker-test program itself is silencing the hdmi output with some driver call....I'm really doubtful. I hope you don't mind me saying so. For a couple of reasons, but mainly: The audio stops 10 minutes after boot time even if there is no audio process running at the time. For example, I can run speaker-test before 10min mark to prove audio comes out right after boot. Then turn off speaker-test before the 10min mark, and run it after. There is no audio. Do I understand you correctly? That is, strace speaker-test? ...or maybe I should strace another process that maybe disabling sound. Guessing which one is the root question anyway.
