ubuntu on Raspberry PI 4 [ARM64] : autodetect failed #540

I have Ubuntu installed on a Raspberry PI4 and CEC fails to work. The HDMI port/TV surely supports CEC b/c it's the same HDMI port used by an Apple TV that works with the TV remote. Is this a bug or Ubuntu/Raspberry PI4 is not supported?

The error is:

$sudo cec-client
No device type given. Using 'recoding device'
CEC Parser created - libCEC version 6.0.2
no serial port given. trying autodetect: FAILED

uname

Linux 5.8.0-1007-raspi \#10-Ubuntu SMP PREEMPT aarch64 aarch64 aarch64 GNU/Linux

if you don't need ubuntu you can 'sudo apt install cec-utils' on raspbian and it will work. But also experiencing this on ubuntu 20.04/Pi4
