Headphone jack vs touch display - petriiczech - 11-09-2024
I ran into a problem that I couldn't find here.
If I want audio output to the headphone jack, which is not available by default on the RPI4, I have to switch: changed Settings > System > Startup Options > Integrated audio from Kernel mode (default) to Firmware mode (Legacy).
Now Headphone jack appeared on the available output list. Selected it and all works fine.
Unfortunately, after that the original 7" display stops working and there is only a black screen, including boot.
Am I doing something wrong somewhere, isn't it a feature?

Prolly a bug. I'll investigate.

Update installed.
A third option appeared:
0: Pi HDMI 1
1: Pi HDMI 2
2: Loopback
Unfortunately, when I try to enter it reports:
Alert
Device is reserved and cannot be selected for output.
Unfortunately, when switching the kernel, the headphone jack appears, but the screen remains black.

Its not obvious to me what might be happening. Maybe someone else will be able to reproduce your issue and provide some insights.
