Can confirm the bug on Lenovo g50-80. Alsa-hda-dkms package doesn't help (there is no "Inverted Internal Mic" entry in alsamixer after reboot).
Removed alsa-hda-dkms and tried "option snd-hda-intel model=auto" but it doesn't help. Workaround "mute right channel" works but can it be fixed permanently (I don't want to manually mute right mic channel every time I use skype)? ** Attachment added: "Alsa-info" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1002978/+attachment/4490701/+files/alsa-info.txt.oHiYSKycn0 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1002978 Title: [meta-bug] Inverted Internal microphone (phase inversion) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1002978/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
