@Hui There is longer version of dmesg in the data that automatically collected, so I assumed it's good, but anyway I attach here a full dmesg log after system startup.
I also repeat that alsa recognizes the devices: $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: sofhdadsp [sof-hda-dsp], device 0: HDA Analog (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: sofhdadsp [sof-hda-dsp], device 1: HDA Digital (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: sofhdadsp [sof-hda-dsp], device 3: HDMI1 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: sofhdadsp [sof-hda-dsp], device 4: HDMI2 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: sofhdadsp [sof-hda-dsp], device 5: HDMI3 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 but pulseaudio doesnt: $ pacmd list-cards 0 card(s) available. Whats the reason to downgrade the kernel? I have never tried it and actually afraid it will mess up my system (or sound again...). Not sure how to do it also. ** Attachment added: "dmesg.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1886696/+attachment/5390844/+files/dmesg.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1886696 Title: [Vostro 5490, Realtek ALC3204, Speaker, Internal] Pulseaudio fails to detect card To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1886696/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
