I've had an HP Spectre 360 with HP dock for 5-6 years, and this has always been a problem, and it still is. I traced it down one time to the script that detects the available audio input devices, and sets the default. The script is poorly written and is hard to follow. It detects that there are two microphones. Then correctly sets the default microphone to what the user specified, but then it sets it again, to the last microphone detected. In my case, it was the non-existant microphone on the HP dock. This script got written over by some update, and I haven't had the time to track it down again.
I'm still seeing this in 20.04 beta, the difference is now it no longer remembers my selections for using the internal speakers, or the internal microphone. It defaults to the non-existent dock speakers and microphone every time I reboot. The only way I could get the internal microphone to work was if I booted without being attached to the dock, then attach the dock after I logged in. -- 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
