3.5mm headset microphone detection failure #294

Open j-o-h-n-g opened 1 month ago

j-o-h-n-g commented 1 month ago

My 3.5mm headphones work reliably but the microphone is often not detected. I can sometimes get this to be detected after many removals and inserts. Then it works fine until I next reboot. This seems to be at the kernel level rather than anything in userspace. dmesg output below. This has been occurring since I first installed asahi (everything works fine in MacOS). Reporting now as recently upgraded to fc40 and still occurring.
