Apologies offered, the forum software was giving me a 524 timeout error when I tried to post this, I did not see that it was anyway posting multiple versions... So, so sorry...
Hello!
I am using an RPi 4 in a dual headed scenario, I can't upgrade my HDMI 1.4 Denon AVR-2310 (2009) at the moment:
- RPi 4 4 GB
- TV on HDMI0
- AVR on HDMI1
- nightly-20210426-090e00d
I am switching from a 2007 Toshiba FHD TV to a new Sony XH90 4K HDR.
I am experiencing an EDID issue. I had mentioned it a few days ago, but this time I have debug logs and data points, as well as a work around:
Case 1 - Single headed - Toshiba 1080p TV - Video and audio through AVR - Working
- Pastekodi - http://ix.io/3ewO
- EDID Denon AVR - DenonOnPi4-EDID.bin
- EDID Decode Denon AVR - Ubuntu Pastebin
Case 2 - Dual headed - Toshiba 1080p TV - Video to TV, sound through AVR - Working

Case 3 - Dual headed - Sony 4K HDR TV - Video to TV, sound through AVR - Video OK, no sound on AVR

Case 4 - Dual headed - Sony 4K HDR TV - EDID trick - Video to TV, sound through AVR - Working
- Pastekodi - http://ix.io/3lhu
- EDID Denon AVR - https://www.youplala.net/~nico/LE10/DualDenonOnPi4-EDID.bin - From Case 2, forced
- EDID Sony TV - Dual4K-SonyOnRPi4-EDID.bin
- EDID Decode Denon AVR - Ubuntu Pastebin - From Case 2, forced
- EDID Decode Sony TV - Ubuntu Pastebin
The AVR EDIDs of Case 2 and 3 are quite different.
It's to be noted that the AVR also has its output connected to the TV. I'm guessing that it is creating an EDID mixing the TV's capabilities. In case 3, that must be confusing LE10 no ends. But is it really LE10's fault? I'll leave that to your judgement.
My workaround is to use getedid and acquire a working AVR EDID, then manually force it upon LE10. I'm afraid that I may gather mismatched delay data on the way and have weird lip sync... But heh, still better than no sound!
Have fun with this!
Thanks!
