@hui.wang Sorry for the late response.
I have now managed to make my headset mic work permanently. I had to add the following line to the file /etc/modprobe.d/alsa-base.conf: options snd-hda-intel model=alc295-hp-x360 However, after doing this, a week later my speakers stopped working and I had to change some pin mappings using alsa-tools-gui: specifically I used Pin 0x14 for Internal Speaker (LFE) and Pin 0x1e for Internal Speaker. So right now, my speakers work, my headset(mic + sound) works and only my internal mic does not work. I am still unable to run the dump program in Windows. However, I can tell you that my laptop has Intel Smart Sound Technology(SST). I read somewhere that Ubuntu still does not have proper support for that although I may have misunderstood what I read. So I am not sure. -- 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: New 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
