For a fix that worked for me, see https://askubuntu.com/questions/1218136/internal-microphone-doesnt-work- when-using-headphones/1285982#1285982.
The fix: 1. Run sudo apt install alsa-tools-gui hdajackretask 2. Select the appropriate sound card up top in Select a codec. 3. Then make the Black Mic (headphone jack) override Not connected. 4. Lower right corner, select Install boot override. 5. Then reboot and test. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1025388 Title: Internal mic stops working when plugging in headphones Status in linux package in Ubuntu: Confirmed Status in pulseaudio package in Ubuntu: Confirmed Bug description: I am currently running Quantal and when I plug headphones into my headphone socket (which has an icon of a headset next to it, so I presume it can take some kind of headset), the internal mic on my laptop stops working. If I unplug the headphones the internal mic works as normal. I tried this with two different sets of headphones (one of which has a mic, and the other I think has a mic too).
