Bug Description
I have a Lenovo Thinkpad X1 Carbon (2nd gen, 2014?) running Ubuntu Yakkety (16.10). Kernel is the most current one: 4.8.0-39-generic #42-Ubuntu
In the last days the microphone stopped working when I am on the Google Hangouts video conference in the Chromium browser. I checked the sound settings of the System Settings and on the "input" tab the slider for the microphone volume is grayed out and cannot be moved away from the zero position. The microphone level monitor bar does not move when talking or touching the microphone.
Then I found the following on the internet
http://
and tried to solve the problem following the hints:
- Reboot does not solve the problem.
- I could not do any tests with gstreamer-
- pavucontrol (Pulse Audio Sound Control) shows on its "Input Devices" Tab that the microphone of the laptop is OK and that the kernel works with it. The Level monitor bar is moving according to environment noise and touching of the microphone.
- "sudo alsa force-reload" does not solve the problem.
- "sudo apt-get remove --purge alsa-base pulseaudio; sudo apt-get install alsa-base pulseaudio ubuntu-desktop" and reboot afterwards does not solve the problem.
- audacity is recording through the microphone correctly.
- Adding "options snd-hda-intel position_fix=1" to /etc/modprobe.
I hope that is a known problem. Please tell me if you need further information.

Luke, I have followed your instructions of PuleAudio logging during system startup on
https:/ /wiki.ubuntu. com/PulseAudio/ Log
After booting the system I got 4 log files which I will attach.
The "Input Volume" on the "Input" tab of the Unity Sound Settings is still grayed out.
