Same issue, fabianbur's fix didn't work for me. Lenovo Ideapad 305 15IBD Windows 7 and Ubuntu 16.04 dual boot.
This day that I'm posting this is the first time I've encountered this issue, and it's really annoying. Was working fine until now, the only thing I've modified and could have triggered this to happen, was enabling the echo-cancellation in PulseAudio, as seen here: https://askubuntu.com/questions/18958/realtime-noise-removal-with- pulseaudio Otherwise I have the same experience as Denilson Sá (denilsonsa) above, alsamixer works fine, but only 'Capture' and 'Internal mic boost' comes up as input, regardless of jack plugged in or not. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1359803 Title: External mic not being used in combo port Status in linux package in Ubuntu: In Progress Bug description: I'm using Ubuntu 14.04 on my Asus 1015E that only has a combo audio port which accepts smartphone type "headsets" (3.5mm TRRS headphones with mic on the same wire). Ubuntu does not deactivate the built-in mic when I connect my headset. It doesn't even use the headset mic and instead keeps picking up audio signal from the integrated microphone (that's on my laptop bezel).
