The microphone works perfectly on Windows 10 (present in Dual boot mode). Initially, Internal Microphone was not even detected but installing alsa-tools-gui and overriding pin 0x12 to the Internal Microphone fixed that issue. [Pin 0x13 does not work and causes static in a headphone if it is plugged in.] Microphone is not able to pick up any sound. I changed levels/settings in alsamixer, pavucontrol without any success: In alsamixer: Experimented with levels ranging from very low to very high for Internal Mic, Capture, etc. In pavucontrol: Set the Internal Mic as a fallback device, unlocked the channels for the mic, experimented with reducing the level for one of the channels (reduced right mic level to Silence while keeping the left mic level normal/high and vice versa). alsa-info: http://alsa-project.org/db/?f=cf6d3ccc6372f955da7d99df07afbcb31d5a6c7f arecord -l **** List of CAPTURE Hardware Devices **** card 0: PCH [HDA Intel PCH], device 0: ALC285 Analog [ALC285 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1840725/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
