Think I've figured it out - it will play sound when I select interlaced resolutions (1920x1080i, 480i etc) but not when I use standard progressive scan ones (1920x1080p).
I was going to get a better TV anyway but thanks for all your help
One last Question to Mr. Da Flex:
How can you chose a resolution of 1920x1080 (it doesn't matter if "i" or "p") on a Screen that is only "HD-Ready" and has a native resolution of 1366x786 ?
I though there is this "EDID-File"
Extended Display Identification Data - Wikipedia
for Display Devices which describes their capabilities to a video source and was "transferred" during the "HDMI-Handshake".
So if the TV send this EDID-File to the PC, in LibreElec only a max. Resolution of 1366x786 would be possible.
Or did I get something wrong here ?
Is there a Difference between a TV and a Laptopdisplay `?
Like you know, I tried to install LibreElec 10.0.1 on my Asus Eee-PC and I couldn't get a Resolution of 1280x720 or even 1920x1080 out of it because the Display only has a native max. Resolution of 1024x600.
