You have been subscribed to a public bug:
Hello,
After updating to the following kernel versions:
linux-image-6.8.0-41-generic 6.8.0-41.41 amd64
linux-image-generic-hwe-24.04 6.8.0-41.41 amd64
I encountered an issue where the module that allows selecting
microphones (for example, in audio settings or via PulseAudio) stopped
functioning correctly. I had added the following module option to enable
microphone selection on my asus tp-550ld laptop:
options snd-hda-intel model=dell-headset-multi
This configuration worked perfectly in previous kernel versions,
allowing me to select and switch between different microphones. However,
after the update to kernel version 6.8.0-41, this functionality broke.
To resolve the issue temporarily, I reverted to the previous kernel
version:
linux-image-6.8.0-40-generic 6.8.0-40.40 amd64
After switching back to the earlier kernel, the microphone selection module is
working again as expected.
Please let me know if further information or logs are needed to
investigate this issue.
Thank you for your assistance.
Best regards,
