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!
