Hi,
yesterday I've performed a system update on my RPI4 and eventually pacman recommended a change in /boot/config.txt by including a kodi-include-file with several configuration statements.
My RPI4 is running as music-player-client in a snapcast-environment (partly headless: no display, but with a HDMI-extractor for audio signals). The update yesterday completely broke the audio functionality due to the overlay change: before the update I used "vc4-fkms-v3d", but now the kodi-update includes
dtoverlay=vc4-kms-v3d,cma-512
dtoverlay=rpivid-v4l2
Now I am not able to get sound out of my RPI4:
- all the audio-device names changed -> so all applications are misconfigured now: annoying, but I'm able to fix that
- /opt/vc/bin/tvservice cannot find devices although "hdmi_force_hotplug=1" is set.
$this->bbcode_second_pass_code('', '/opt/vc/bin/tvservice -l
0 attached device(s), display ID's are :')
The previous overlay vc4-fkms-v3d was able to find a display
$this->bbcode_second_pass_code('', '/opt/vc/bin/tvservice -l
1 attached device(s), display ID's are :
Display Number 2, type HDMI 0')
So HDMI seems to be dead or in some power-off-mode and can't be powered on:
$this->bbcode_second_pass_code('', '/opt/vc/bin/tvservice -p
Powering on HDMI with preferred settings
[E] Failed to power on HDMI with preferred settings')
Any help to configure this overlay and HDMI correctly would be appreciated. Or is the only solution to uninstall kodi and return to the fkms-overlay??
