Upgrading from Pi2 to Pi4 - No sound and CEC takes a few minutes to work if at all

    Hello All,

    I'm a long time Pi user and have never had any issues relating to sound or the CEC. Short version: recently purchased a new Pi4, installed the latest image for Pi4 - LibreELEC-RPi4.arm-9.2.5.img, booted it up but now have no sound and the CEC takes about 5 minutes to work. I do have a keyboard/mouse attached - both work fine so at least I can move around within the app. In addition when I reconnect my Pi2 using LibreELEC-RPi2.arm-9.2.4.img,everything works as it should - instant sound and CEC response.

    Any help resolving the sound/CEC issue on the Pi4 would be welcome. If more detail is required (logs for example) pls let me know.

    Thanks in advance!

    Thanks for replying, much appreciated!

    I've tried both ports, doesn't matter. I've now moved the hdmi cable from hdmi 2 to hdmi 1 on my samsung smart tv, seems to be working now! The old PI worked on any hdmi port on the tv.

    Perhaps I can close this thread.

    I'm having a smiliar problem. I've had 2 Pi4 boxes for a while now, then suddenly on the same day they both stopped outputting sound.

    I checked everything, then eventually did a clean install of 9.2.5 and upgraded to Leia 18.8. Still no sound.

    Interestingly, a clean install of Xbian works just fine. :/

    However, I don't know if this is expected behavior or not, but I can only connect to the left side micro HDMI. The right side (closest to the power plug input) has never given me a signal. This has always been the case on both boxes, even when the sound was working.

    I've posted a log, hope I did it right. Any suggestions would be appreciated.
