Please test v3 kernel: https://people.canonical.com/~hwang4/25skipi915/v3/
I guess v3 kernel will work successfully, after boot up, you could run alsa -l to check if there is valid sound card. and pulseaudio will have an error on your machine, so if the kernel has no error, please backup /usr/share/alsa/ucm2/sof-hda-dsp/Hdmi.conf, and I uploaded a new Hdmi.conf in https://people.canonical.com/~hwang4/25skipi915/v3/, please copy this file /usr/share/alsa/ucm2/sof-hda-dsp/ then reboot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1874698 Title: [OMEN by HP Laptop 15-dh0xxx, Realtek ALC285, Black Mic, Left] Recording problem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1874698/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
