I can't believe it, it works now with position_fix = 3! I don't know if this was caused by the additional patch to the kernel, I'll probably try to remove it to see if it is still working with 3, but I had already tried all position fix and a heap of other stuff. The audio now is perfect, even with pulseaudio :) This is the result that you have requested anyway: 0: Same problem, no other issues 1: Same problem, no other issues 2: Unable to acquire stream, arecord signal overrun!!! (at least 377,780 ms long) and no audio is acquired 3: No clicking in the acquired stream! 4: Same problem, no other issues -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1801540 Title: Microphone distorted sound on ALC892/1220 on AMD chipsets To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1801540/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
