Bookworm w/ Kernel 6.6.47: Build successful, Audio works; Service and Headphones fail

[Tilogorn]

Hi guys,

I've read through all "kernel xy build fails" issues, but I have the feeling this is a new issue. Building the binary works, using the soundcard as speaker output in the system works. But the phone jack does not work and (re)starting the wm8960-soundcard.service results in exit code 99 (which is related to the non-functional phone jack, I believe).

My setup: Raspberry PI 5 with WM9860 HAT and recent Rasperry Pi OS (released 2024-07-24)

Linux spotify-player-raspbian 6.6.47+rpt-rpi-2712 #1 SMP PREEMPT Debian 1:6.6.47-1+rpt1 (2024-09-02) aarch64 GNU/Linux

I can narrow it down. One can just do this in the cloned repo:

~/WM8960-Audio-HAT $ sudo ./wm8960-soundcard
+ exec
++ basename ./wm8960-soundcard
~/WM8960-Audio-HAT $ echo $?
99

I am a software developer myself, but my knowledge of C is limited. I cannot find the exit code of 99 in wm8960-soundcard.c. But I am willing to change/recompile/add debug output if anyone guides me to get a more precise error message.

Since the combination of a small amplifier with speaker and headphone output, powered by the Pi on a single HAT seems a unique combination on the market, I am willing to support the fix of this issue financially. After all, it will improve the Christmas present for my son. :-)

I have the same issue, tried with a Raspberry Pi 4, Raspberry Pi Zero W2 with 3 different HAT. I install a Debian lite via Rasberry Pi imager, follow the documentation to install the board and have this error 99

[Tilogorn]

Can one of the maintainers confirm that the service issue might relate to the phone jack issue?I am just assuming this because the WM8960 wiki page tells to restart the service if the phone jack does not work.

I have same issue, Rpi4 with Raspiaudio HAT (based on WM8960-soundcard). Reinstalled OS and started from scratch many times, still cannot go further. I have notice that in most of the cases aplay and arecord works fine.
