I had the same problem on 2 computers with same chipset. Russell Treleaven helped me on Alsa bugtracker : https://gitlab.freedesktop.org/pulseaudio/pulseaudio/issues/617 He found that when Pulseaudio Capture level is more than 21%, Line boost, Mic Boost and Internal Mic Boost are always at Max in Alsamixer and then, nothing is recorded. With Alsamixer or Pavucontrol, it's possible to set correctly all levels and to activate Capture 0 and Capture 1.
But each time I'm using again Linux Mint MATE or Ubuntu sound control panel, if I put Pulseaudio Capture level at more than 21%, capture doesn't work anymore again ! -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1591535 Title: [Satellite A215, Realtek ALC268, Mic, Internal] No sound at all. My built-in internal mic won't record sounds. Status in alsa-driver package in Ubuntu: Confirmed Status in pulseaudio package in Ubuntu: Confirmed Bug description: My built-in internal mic on my Toshiba Satellite-A215 will not pick up sounds. The external speakers work just fine, but once again the mic can't record any sounds. I have an Ubuntu 14.04.4 LTS.

The same Ubuntu forum user suggested I file a bug. He/she provided me with a link from "an old report from an A215 with the same ALC268 codec": https://bugs.launchpad.net/ubuntu/+s...r/+bug/1081353 I provided this because it may be helpful in the debug process. The version of ALSA I have is shown below: Advanced Linux Sound Architecture Driver Version k3.19.0-61-generic. Any help would be appreciated, please let me know if you need any additional info.
