No HDMI sound but sound through headphones

[trtsmb]

My sound was working perfect up until a few days ago. I plugged my earbuds in to listen to something and since then I cannot get sound through HDMI .

I've tried the recommendations on ItsFOSS but no luck. If anyone could give suggestions, you would make my day.

Have you checked already the settings under "Configuration" tab in PulseAudio Volume Control (pavucontrol)?

PulseAudio shows this:

Screenshots often are not that useful. Is that the only option in that popdown menu?

It's a big long list of options from Analog to 7.1 Surround Sound. The dropdown menu won't let me take a screen grab to show all the choices.

Are you using the onboard HDMI/ Built in audio? or from the Graphics card?

The later you should turn off the built in audio , should be one of the options. then disconnect the hdmi and reinsert it , it should work.

I have an integrated graphics chip. All I originally did was plug the HDMI cable into the HDMI port on the back of the Nuc and sound worked fine up until a couple days ago.

I tried uninstalling alsa and pulseaudio and then reinstalling. This didn't work.

See if this helps any:

aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Center.wav

If nothing, change 3 to 7. Still nothing, change 7 to 8. Still nothing, change 8 to 9. Lastly, change 9 to 10.

Which, if any, worked?

No joy for 3 or 7-10 .

I want to thank everyone for their help. Sound is working again.

WOW. Any idea how?

If I knew what the magic was I'd write it down in case it happens again .
