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

Can confirm I have the same issue on my Dell laptop with HWE kernel 6.17.0-14.14~24.04.1
No analogue audio via the 3.5mm jack.

I don't have 6.17.0-12, but rolling back to 6.14.0-37-generic fixes the
issue for me.

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

Status in linux package in Ubuntu:
Confirmed

Bug description:
Since the last kernel update, the analog audio output (headphone jack)
has stopped working. 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.
