kernel already has a valid sound card, but pulseaudio doesn't have.

Please edit /usr/lib/systemd/user/pulseaudio.service

comment out the existing line starting with ExecStart and add a new one ExecStart=/usr/bin/pulseaudio -vvvv --log-target=file:/tmp/a.txt

reboot

upload the /tmp/a.txt

thx.

It seems there is no hw:sofhdadsp,6 on this device.

[Hui Wang (hui.wang)]

On your machine, there is a internal mic connected to the codec, so please try with "snd_hda_inte.dmic_detect=0".

[Hui Wang (hui.wang)]

"snd_hda_intel.dmic_detect=0".

[Hui Wang (hui.wang)]

This is a linux kernel bug instead of a pulseaudio bug, there is no dmic connected to the PCH, so the kernel should uses the legacy hda driver on this machine.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1879462

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

@hui.wang

I try to add line 'options snd_hda_intel dmic_detect=0' into /etc/modprobe.d/alsa-base.conf. The pulseaudio can load module-alsa-card successfully. However, the kernel complain that the dmic_detect is not a good way to config the driver.

kchsieh@kchsieh-Inspiron-3790:~$ dmesg | grep snd_hda_intel

You could change using "snd-intel-dspcfg.dsp_driver=1". But this issue will be fixed in the kernel, after that you don't need to add those kernel parameters anymore.
