HDMI audio output device(s) disappeared

Hi, I'm using Libreelec 10.0.4 on a raspberry pi 4 8gb

I nearly finished my setup after hours of fiddling. But after I installed some add-ons today suddenly all the HDMI audio output devices in the Kodi settings are gone and I'm now left with only the headphones (which I enabled via the config.txt before) and Bluetooth as audio output. I'm pretty sure it has something to do with the Audio Profiles add-on I installed from the Kodi add-on repository. At least I recognized it afterwards and it was the only audio output related add-on I installed today.

Before everything was working fine and I had multiple hdmi audio output options.

I already reinstalled the add-on, uninstalled it, rebooted, tried to change the audio output device to hdmi in the guisettings.xml and searched for hours in the internet for a solution, but couldn't find a fitting one.

The weirdest thing is, if I reboot the sound is played over hdmi but as soon as I go to settings/audio (not doing anything else) the sound is gone and the audio output device is still bcm 2835 headphones.

Please could someone help me, I don't want to do the whole setup all over again.

Btw. I'm not the most advanced Kodi or Linux user so please be as precise as possible

So I tried deleting the directory over sftp, but it didn't exist anymore because I already uninstalled the add-on

I reinstalled it, to see what's in there, but there's only a settings.xml

deleting the guisettings.xml also did nothing

aplay -L outputs this

If this is any help to you

Okay I solved the problem by doing a backup with the backup addon (after the problem occured), a fresh Libreelec install and restoring everything except the config folder and guisettings....so I "only" had to do all the settings again.

Anyways today the issue came up again and after some troubleshooting I could definitely identify the snapclient add-on to be the source of the problem and not the audio profiles add-on.

I was setting up a snapserver/client when it happened and I think I installed these add-ons as well, when it first happened. So the problem must have only been solved because some add-ons don't work properly after restoring a backup and have to be reinstalled.

Uninstalling the snapclient and rebooting brings back all the lost audio output devices.

After doing some research about how to get the snapserver/client running properly I found this thread

Snapserver/Snapclient does not work on RPi4 with LE 10.0.1 via HDMI

Dear all,

maybe a problem someone else had already solved: Today I've been putting an RPi4 with LE 10.0.1 into action on a new Marantz NR1711 connected via HDMI0. With Snapclient deactivated on this machine, I can see via Settings -> System -> Audio -> Device the following entry which I picked: "ALSA-vc4-hdmi0 (vc4hdmi0), MJI marantz-AVR on HDMI". So far anything works like charm.

Since this device is in the living room and I do have an additional RPi3 in the kitchen/dining room running a…

which describes the same Problem

So the problem seems to already be there for a long time.

Isn't there anyone with a running snapserver/client setup, who can give instructions how to set it up correctly and how to solve the audio issue? ...Please?
