Can you attach the output of "pactl list cards"? Please use the "Add an attachment" link instead of pasting the text in the comment box, so that the comment thread stays easy to read.

Actually, "pactl list" output would be better than "pactl list cards". Run the command when you're playing something and you'd expect the audio to be audible via HDMI.

The sound is just working again, magically.

Please, let's *not* close this bug yet as I have the feeling it's going to stop working again anytime soon and then I'll be able to provide you the asked logs.

Thanks, Tanu!

pactl list when playing something (but there's no sound)

I've attached `pactl list` output when playing something and there's no audio (although it was expected to be audible via HDMI).

Everything seems fine in the pactl list output.

Try if this command makes any noise (it should play white noise):

    aplay --device=hw:0,7 --format=cd /dev/urandom

Before running that, turn down the volume of the speakers (at the speaker end of the hdmi cable, not on your computer), because it can be really loud.
