@c0rnelius new test with latest debian rolling (25.8.0-trunk.5_Bananapim4zero_trixie_current_6.12.23_minimal): 
- HDMI audio and GPU ok 👍
- no wireless
 
Again my question about overlays: do I need another overlay for wireless? The one I used for standard builds (sun50i-h616-bananapi-m4-sdio-wifi-bt) is not working...
 
Thanks for your help.

The issue appears to be two things.
 
These two patches and the current defconfig(s) being used.
drv-rtc-sun6i-support-RTCs-without-external-LOSCs.patch
drv-rtc-sun6i-Add-Allwinner-H616-support.patch
 
When I disable those patches and use my own defconfig everything works as it should.

The hard part here would be figuring out exactly what in the defconfig(s) are either breaking things or missing. Also if I disable those patches, what does it break on other units? I'm under the impression these patches were rejects from the original h616 bring up in mainline. But I could be wrong?

@ScoreABSM  If you enable overlay via armbian-config remove "sun50i-h616" in boot enviroment(armbianEnv.txt) 

should be look like this
overlays=bananapi-m4-sdio-wifi-bt

There are big differences between the two revisions. The biggest one is, one is using Wifi/BT over USB and the other SDIO, which requires the sdio overlay. The reason for BT not working on Armbian, I have yet to figure out. Like I said before, it works on (my personal) a more minimal build;

It is hard for me to determine the reasons BT doesn't work, as the patching is very extensive. If it is even the patching?
 
And yes I include the BT node in the overlay; https://github.com/armbian/build/blob/main/patch/kernel/archive/sunxi-6.12/patches.armbian/Add-BananaPi-BPI-M4-Zero-overlays.patch#L267
 
As for HDMI audio and GPU, the PR I posted a link to corrects this. In future releases and rolling (give it a day) it should now work. Although I think I need to now add my changes to the 6.14.y branch? I'll check.
