That's a good discovery. This change makes sense, as the different of PRESET_ATI_SB from PRESET_AMD_SB is about the position reporting. ATI_SB uses the legacy LPIB register read while AMD_SB uses the position buffer table. This could be verified by changing position_fix module option: 1 is LPIB and 2 is position buffer.
If we can confirm that this change generally improves the behavior, I can merge the fix quickly to the upstream. Can anyone else check it? -- 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
