[Bug 2141634] Re: [Regression] Analog Audio Jack (3.5mm) not working after Kernel Update - Works on previous Kernel

Okay maybe another workaround if you have this issue. I managed to restore analog audio after booting without the headphones connected. I did so by running this command: systemctl --user restart pipewire pipewire-pulse.service pipewire-pulse.socket pipewire.socket -- You received this bug notification because you are subscribed to linux in Ubuntu.

Other audio outputs like internal laptop speakers and USB-C audio continue to work fine. The Problem: When using the new kernel, there is no sound from the 3.5mm jack. A background process repeatedly reports the following error: Error: command ['pacmd', 'list'] failed with exit code 1: No PulseAudio daemon running. Evidence of Regression: This issue does not occur when booting with the previous kernel version. All audio outputs, including the 3.5mm jack, work perfectly there.
