Since it's the same codec alc255 I assume the issue is shared? I already have a temp fix which is working fine at the moment and there are already too many similar threads with 0 progress for many years.
So, doubt a new bug report will do any good. I just shared my results here, will wait patiently for OP to respond or this thread gets closed due to inactivity. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1918142 Title: Headphone microphone doesn't work - ALC255 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1918142/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
