Ah, that sounds likely. Not quite sure how passthrough works.
i have the same result,HDMI 1can hear,but only two channelcocodude wrote: ↑Thu Sep 26, 2019 9:18 pmI've been trying to do exactly this.
It does seem to work in general; I can quite easily get 4kp60 video out on HDMI 0 and some sound out on HDMI 1 (if I right click on the speaker icon on the desktop and change the output to HDMI 1). However, whatever I try, I think I can only send two channel PCM to this. I can't passthrough any other sources like Dolby Digital using Kodi, VLC or anything really.
Passthrough appears to work just fine when both video and sound are going through HDMI 0.
Old thread I know, just confirming you have video output on HDMI 1 and passthrough on HDMI 2 to an AVR?
How did you achieve this, I can't get it to work, I have a Denon AVR which is detected by libreelec nightly on HDMI2 (works fine with video/audio combined on the same hdmi port), but no audio passthrough output on HDMI2 when Video on HDMI1? Thanks for any info.
It appears that 16th August 2020 nightly was successful (https://forum.libreelec.tv/thread/22302 ... post143378).
