Public bug reported:
At some point the internal microphone has stopped working on my Dell
Precision M4600. Sorry I can't pin point exactly when, but I first
noticed it about two weeks ago. I've tried everything I can think of,
uninstalled and reinstalled every package I can think of that is
connected to sound. Happy to try anything else.
If I use my old 24.04 install media, which was created before Christmas
I think, but I'll see if I can work out when and add it to this report.

** Affects: alsa-driver (Ubuntu)
Importance: Undecided
Status: New
** Description changed:
At some point the internal microphone has stopped working on my Dell
Precision M4600. Sorry I can't pin point exactly when, but I first
noticed it about two weeks ago. I've tried everything I can think of,
uninstalled and reinstalled every package I can think of that is
connected to sound. Happy to try anything else.
If I use my old 24.04 install media, which was created before Christmas
I think, but I'll see if I can work out when and add it to this report.
