Upcoming moOde 9.0.0 (Bookworm)

[challenge]

Comment out the kms driver in config.txt, reboot and then Headphone should show up in aplay -l and be in the drop-down list in Audio Config.

raspberry pi 4 b+ 1GB, r900 pre6 img
commented dtoverlay=vc4-kms-v3d, seems fine (headphones are back):

Code:

pi@moode9:~ $ aplay -l

 EDIT: 
after I comment out the kms driver, reboot, the output menu shows the first hdmi correctly as shown above, but if I try to play it throws an error: 
"Failed to open "ALSA Default" (alsa); Failed to open ALSA device "_audioout": No such device"... 
the drop down menu item (e.g. 0: Pi HDMI1) is very likely pointing to the wrong interface, only when kms is commented.
It's like it's picking the first from the aplay-L list, "_audioout", instead of the correct hdmi one.
Even if I reapply or toggle to HDMI2 and back, it still points to the wrong non-hdmi alsa output.
This happens only when choosing HDMIs in the output dropdown and kms commented out.
If I pick "Pi Headphones" it plays fine.
