@Hui "And from -42, it enabled the dmic_detect by default. And it introduced a regression from stable patches. It is fixed in the -46." As per my post #6 - it's not fixed in -46 kernel.
So I deleted dmic_detect=0 from alsa-base.conf and created a symbolic link as per post #10. Rebooted. I did get sound, but it feels like it's very quiet comparing with the legacy driver (I can't hear anything below 40% volume setting and barely can hear sound at 50% setting). Also I found that microphone was enabled by default after reboot and I don't like that. So overall I'm not happy with this solution and will get back to legacy driver (dmic_detect=0 in alsa-base.config). Output of dmesg is attached and here is also an aplay output: user@G3:~$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: sofsklhdacard [sof-skl_hda_card], device 0: HDA Analog (*) [] Subdevices: 0/1 Subdevice #0: subdevice #0 card 1: sofsklhdacard [sof-skl_hda_card], device 1: HDA Digital (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: sofsklhdacard [sof-skl_hda_card], device 3: HDMI1 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: sofsklhdacard [sof-skl_hda_card], device 4: HDMI2 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: sofsklhdacard [sof-skl_hda_card], device 5: HDMI3 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 ** Attachment added: "dmesg_output_v46_with_symbLink.csv" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1868319/+attachment/5351257/+files/dmesg_output_v46_with_symbLink.csv -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1868319 Title: PCI/internal sound card not detected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1868319/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
