@flohack Yes, I forgot that the rootfs is the same across different halium versions.
But I wonder if it still isn't possible, that some components like pulse are used differently.
For example, why does it claim, that no pulseaudio deamon is running for ierihon, while it lists sinks for me on bq 4.5 and FP3?
And isn't it also about kernel modules for a common audiochip, which could be supported by a newer kernel?
Edit:
Ah, you said that they do not upgrade the kernel,
I thought you was talking about vendor blobs.
