Re: [tlug] No sound with HDMI connection

["Daniel A. Ramaley" <daniel.ramaley@example.com>]

I don't know about Mint specifically, but most Linuxes these days use
PulseAudio. Sometimes, if you run "pavucontrol" you can fix problems
like this. My media PC occasionally has an issue similar to what you
describe. The fix for me has been to run pavucontrol then click the
Configuration tab and then choose a Profile that lists the HDMI output.
Try a few different Profiles and maybe one will work.

If you find a working Profile, remember which one it is for when you
have to do this again--every so often PulseAudio will automatically
switch itself to a broken Profile, so one has to go in and fix it again.
This is normal/expected behavior when using PulseAudio, though i have
not yet figured out why such behavior is desirable.
