Same issue on Dell G3-3590 i7 gtx1660, worked for 2 months and now simply stopped, started without audio that i solved with this:
" I used to change /etc/default/grub to have this line GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet splash acpi_backlight=vendor acpi_osi='!Windows 2013' acpi_osi='!Windows 2012' snd_hda_intel.dmic_detect=0" Then run in terminal grub-mkconfig -o /boot/grub/grub.cfg " I get this solution from here: https://bbs.archlinux.org/viewtopic.php?id=251157 Now audio works fine, with and without headphone. But the problem now is that the internal microphone is not detected. And when the headphone (with dont have microphone) is connected he is detected in input devices list as if it was a microphone. and when I added this: options snd-hda-intel index=0 model=laptop-dmic on: /etc/modprobe.d/alsa-base.conf a internal mic appears in the input device list but still not detecting audio, and the headphone is not detected in the input list anymore, but audio still working... -- 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
