Had the same issue with an ASUS S551LN (Realtek ALC233, Internal Mic, combo microphone/headphone jack). After playing around a lot, the following settings in the alsamixer finally seemed to do the trick:
1) Playback->Mic: 100% 2) Playback->Mic Boost: 0% 3) Capture->Capture: 100% 4) Capture->Mic Boost: 0% This resulted in what looked like a very low mic level in pulseaudio, but the internal mic works fine. Changing any mic setting from pulseaudio immediately increases the boost in alsamixer and kills mic input. Hope it's of some use -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1334617 Title: [X550LB, Realtek ALC233, Mic, Internal] not working Ubuntu 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1334617/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
