Facing the same problem with an HP Spectre X360, I tested several distributions and several different kernel versions.
I also followed several guides explaining how the problem could be solved, but none worked for me. What I find curious is that in Ubuntu 19.10 and 20.04 in live mode the microphone works perfectly (both internal and the headset). I copied the contents of the alsa-base.conf file from live and overwrote that of the distribution, but it also didn't work. Tested with kernel: 5.0x, 5.3.x, 5.4.x, 5.5x (family 4.x bring other problems for my hardware) I was also able to use an external microphone using a USB adapter. -- 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/1840725 Title: Microphone not working in Ubuntu 18.04.3 LTS on new hp- spectre-x360-convertible-15 laptop Status in alsa-driver package in Ubuntu: Confirmed Bug description: Internal Microphone does not work in Ubuntu 18.04.3 LTS in a new hp- spectre-x360-convertible-15 laptop. 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
