Hi, I tried with the instructions from comment #49 and it almost works
for me.
(You have the kernel versions mixed between 5.3.0-40 and 5.3.0-42 - I
presume that was an accident?)
With Kernel 5.3.0-42 I have no sound at all, and it hangs when I try to shut
down / reboot - might be a different problem.
With Kernel 5.3.0-40 I have sound - just regular stereo as expected, but that
works.
The microphone is detected, but it will not record sound, that is the almost
part.
The funny thing is: If I plug anything into the headset jack - headset
or just plain speakers without a microphone - not only does the output,
and input if it is a headset, work through the jack, but I can also
record from the internal microphone. So the combination stereo speakers
on the headphone jack and internal microphone for recording works.
This is my sound card:
cat /proc/asound/cards
0 [sofsklhdacard ]: sof-skl_hda_car - sof-skl_hda_card
LENOVO-20QD003JGE-ThinkPadX1Carbon7th-20QD003JGE
This is the system info from dmidecode:
Handle 0x0012, DMI type 1, 27 bytes
System Information
Manufacturer: LENOVO
Product Name: 20QD003JGE
Version: ThinkPad X1 Carbon 7th
Is there a trick I am missing, or does the patch still need work?
Happy to provide more info.
