Interestingly, since replacing the kernel with a 6.12 mainline (in casu 6.12.1-061201-generic), I cannot reproduce the problem. Touching wood. This seems workable for me, but of course I'd like the fix to be backported into an officially supported kernel.

The quick "solution" is to restart pipewire (`systemctl --user restart pipewire`), but this comes at the expense of my microphone no longer working in active applications (e.g. Chrome) until I restart them. I had experienced this bug before with mainline kernels for Ubuntu 24.04. I then put it down to those kernels not being optimised for Ubuntu, and reverted to the official 6.8 kernel. However, since upgrading to Ubuntu 24.10 which ships with the 6.11 kernel, the issue has returned, so I believe I can single out the kernel as the culprit.
