[Orange Pi PC Plus] No Audio, No Control

    I have Orange PC Plus and Firstly I installed 12.0.2 LibreELEC and when I connected TV and I didn't hear sound and couldn't control it. But if I switch HDMI port on TV everything works. I read there it can be problem in 12.0.2.

    I installed 11.0.6 and them updated to 12.0.1(because 12.0.1 only works after the update, when I installed 12.0.1 Orange wouldn't boot).

    Today I turned on TV and Orange and LibreELEC didn't see TV and TV resolution was 1024x768, no sound. I restarted Orange but nothing changed.

    When I unplug HDMI on Orange and plug again. LibreELEC said Connected TV, but sound wasn't and LibreELEC resolution list wasn't change.

    Then I restarted Orange again. I could see the correct TV resolution, when LibreELEC booted, the TV resolution was 1920x1080 and the sound was on.

    What's problem?

    Also I want to ask about WIFI and emmc. Why LibreELEC doesn't see WIFI and emmc in Orange PC Plus?

    I think I found a problem. I have 3 HDMI. 2 HDMI are 2m and 1 HDMI = 1.5m. 2m HDMI use for TVs and 1.5m HDMI uses for PC.

    If Orange PC+ use 1.5m it's all ok, but 2m have this problem. I asked chatGPT about it and chatGPT said if 2m has 1+ Ohm it's bad a cable.

    Who has 2m or more HDMI cable can you check it? I checked 18 pin it's power pin.

    0.5m more doesn't make a big difference for electrical resistance. The shielding is more important. HDMI 2.0 and 2.1 cables (4K/8K standard) have better shielding, so get one of those.

    That is more a HDMI cable problem instead an LE. Use a good quality HDMI cable, the quality of the cable it's more important than the length, I seen laptop connected to a "big" TV through a 5 meters long HDMI cable (wasn't a cheap thin cable 8)).... Another thing, some TV's isn't provide EDID (display info) data in stand-by. So, start the TV first, then the LE device. In that case the solution could be to run the "getedid create" command https://wiki.libreelec.tv/configuration/edid#getedid-create
