Hi peyo,
Thanks for your guide. I will check refer to your share site. \

The result is no audio on HDMI.

Since maxwen has replicated what I've done on my LineageOS builds, I'll comment on this. maxwen/proprietary_vendor_brcm@269d6e5 is much more relevant to this. You can either add the 'noaudio' parameter to VC4 or revert android-rpi/kernel_arpi@48fda0f for the bcm2835_audio HDMI interface to be available. That should be enough with the audio HAL that's used on android-rpi.

maxwen/android_hardware_arpi@76add18 is useful if you want to switch between HDMI and 3.5 jack or even use an external audio DAC. How this is handled was changed with the 5.4 kernel.

Hi KonstaT
I have been checking maxwen & android-rpi git source since yesterday.
Your guide will be very useful.
Thanks for your guidance.

I add config value(dtoverlay=vc4-kms-v3d-pi4,noaudio) in config.txt
And I connected hdmi1 port..
The result was a success. The sound is output from monitor or TV using hdmi.
It sounds a little quiet, but it's clear.

Thank you again :)
