Re: Dummy output on my china laptop

Install sof-firmware, reboot, check whether you can reproduce.

Re: Dummy output on my china laptop

Mhm what output do you get from 

sudo dmesg | grep -iE 'snd|sof'
aplay -l
sudo fuser -v /dev/snd/*

Re: Dummy output on my china laptop

Please use [code][/code] tags. Edit your post in this regard.

Why is "snd_hda_intel.dmic_detect=0" ?

Re: Dummy output on my china laptop

Yes, sorry about that. About "snd_hda_intel.dmic_detect=0", I tried some methods from forums for my problem. But it doesn't work

Re: Dummy output on my china laptop

Do you get the "Codec #0 probe error; disabling it..." w/o it?
Resp. what's the inquired outptut w/o that parameter?
What other things "from forums" are currently still activated?

Re: Dummy output on my china laptop

Yes, w/o this i too get this message.
W/o this parameter i got this:

[    0.000000] Command line: BOOT_IMAGE=/vmlinuz-linux root=UUID=cff2e805-0582-4791-9a9d-5e64f0f8c7c5 rw zswap.enabled=0 rootfstype=ext4 loglevel=3 quiet snd_hda_intel.dmic_detect=0

And about "from forums", i also have some strings in alsa.conf and inteldsp.conf
alsa.conf

options snd-hda-intel model=dell-headset-dock

inteldsp.conf

optiond snd_intel_dspcfg dsp_driver=1

Re: Dummy output on my china laptop

It's still complaining about the parameter (just using a different value) and that collides we/ the suggested alnd also set snd_intel_dspcfg.dsp_driver=1
Remove that and the alsa config and post the updated journal to illustrate the baseline situation (don't forget to regenerate the iniramfs, the modprobe.config might be in there)

modprobe -c | grep -v alias | grep snd
