Hi,
I have a RPI4 with the latest version of Libreelec.
When I start some movies the sound channels are wrong. No centre, hard front right, no rear right.
I did already activate the sync to refresh rate. When I did enable this option the first time the audio was fine.
The next day. The audio was with wrong channels again.
If I stop and start the movie the sound is fine sometimes. I must stop and start the movie 3 or 4 times. When the audio channel is right the whole movie plays fine.
Where could be the fault?
Setup
RPI4 > denon avr-x4400h > Philips old tv without acr.
All HDMI cables of course.
Smetske.
