Raspberry Pi 4 HDMI sound stopped working (was fine before)

Hi @mitu thanks for helping out. I have tried to what you suggested but no luck.

Under the ES sound settings I tried the following:

Audio Device: PCM
Audio Device: Master

None of these worked for me.

I rebooted with each try.
I also re-ran the audio configurator and re-selected HDMI with each attempt.
AUDIO CARD is set to Default in the ES Sound Settings.

Should I remove Pulse Audio? Or perhaps uninstall the Desktop altogether?

No, that's not necessary - RetroPie should work with both of them installed. Re-configuring the audio doesn't need a restart.

What's the output if you run aplay -l ?

Call me trigger-hapy, but I uninstalled PulseAudio:

sudo apt purge pulseaudio pulseaudio-module-bluetooth

Now the audio is back on. Also the system is much, MUCH more responsive. Before I used to get a lot of delays/lags when navigating through the menus. This issue is gone now.

@pmdci If you still wish to use the desktop, then make sure to uninstall the lxplug-volumepulse package, otherwise the desktop panel will crash without PulseAudio support.
EDIT: Are you using a PS4 controller (Dualshock) by any chance ?

Seems like the plug-in is not installed...

pi@retropie:~$ sudo apt purge lxplug-volumepulse

I am using an 8BitDo controller. It is incredible but the system is now VERY responsive comparing to when PulseAudio was installed!

I trust I can still use audio on the desktop without PulseAudio?
EDIT: Yes, I can. Just lost my volume mixer :-)

mitu

Try installing lxplug-volume and maybe the mixer will show up again.

I’ve got a similar issue with a new 2gb raspberry. Whenever I upload a rom or restart I lose sound completely. The only way to get it back is put my HDMI cable in a different port on TV and it works again. It’s been doing my head in as cannot find a proper solution.

I managed to just add the default volume widget for the desktop.

I followed your advice and installed lxplug-volume (not the pulse version). I can see it installed some stuff and it also removed some other pulse leftovers (which is good!)

However I didn't see any difference in the desktop for volume. As I said above, I did add a speaker icon at my taskbar before installing lxplug-volume, and it does have one volume slider. Seems like installing lxplug-volume didn't add anything on top of that.

My issue clearly had to do with pulseaudio, which I have no use for (at least for now!) on my current Raspberry Setup.

Your issue might have to do with the different HDMI modes. Have you looked into the config file for all the HDMI settings?
