Hello again!Hello.
My tcl TV suddenly stopped to pass through sound with arc or toslink. If I use the auto setting it passes sound but only DD+ stereo and it doesn't matter what is being played, it's always DD+ stereo.
So I updated the FW to V677, I was using V634( it was ATV 9)
Any one with some insight about this issue?
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
