Hi all,
I'm running Kodi via Libreelec on a rockpro64.
The rockpro64 is connected via HDMI to a Sony 7.2 receiver, which then connects via HDMI to my TV.
When I start Kodi with only my AV receiver turned on (TV off), the blue 'multi channel light on my receiver lights up and I get 7.1 audio. When I turn the TV on it splutters a bit (audio output to receiver cuts in an out) but stays on 7.1 until I go to to play a video. When I hit play on a video it drops back to 2 channels. Starting with the TV on produces 2 channel audio straight away.
Current settings are 7.1 channels with passthrough disabled and stereo upmix turned on. With passthrough enabled the receiver handles DTS OK, however I would like to decode on the rockpro.
I have attached the log file (hastebin) and can see some messages which I think are relevant (below).
Any help is appreciated, thanks!
