TCL C715 HDMI ARC output issue (Low volume) after OTA update

[modsupremo]

I found the software update (May 16, 2022) from TCL EU and wonder if this is the latest.

Hopefully, this will be compatible with my C715.
Thank you so much!

Hello again!
I've found a solution!
It appears that the pcm output was way too low so I accessed the service menu and changed the audio settings as the pics.

In my TV (55EP640) to access the service menu:
Settings->picture->advanced->color and contrast->put the cursor over contrast->press 1950 and the menu will appear.
Hope this helps

Already find the menu also...which parameter should I edit? Has no effect at all for the PCM output...still no sound
