@Raymond I'm sorry, I can't follow what you are saying, I don't know much about hda nor alsa. I confirm that the pin config of 0x19 is required for microphones, without it they are not detected, I just tested it.
@dbyte Did you try what I wrote in comment #34? The problem could be the same and by looking at the output of your alsa-info.sh I think the script I posted will work as intended, but I can't say whether it will get rid of the noise or not. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1252733 Title: [XPS 12-9Q33, Realtek ALC668, Black Headphone Out, Left] Background noise or low volume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1252733/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
