I have an Intel Gemini Lake laptop with N4020 Intel CPU. I'm using latest daily xubuntu hirsute with kernel 5.11.0-13, it recognized everything including wifi and bluetooth, but the problem is I haven't had audio at all. Dead silent.
the pavucontrol shows only dummy output, the vumeter below the volume slider is dancing when i play some audio but there is no sound at all from the speaker. pavucontrol
the output from aplay -l only shows card0 as HDMI :
**** List of PLAYBACK Hardware Devices ****

the output from proc/asound :
cat /proc/asound/cards
0 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xa1110000 irq 133
cat /proc/asound/card0/codec#2 | grep -i codec
Codec: Intel Geminilake HDMI
and the output from lspci only shows this :
lspci -nn | grep -i audio
00:0e.0 Multimedia audio controller [0401]: Intel Corporation Celeron/Pentium Silver Processor High Definition Audio [8086:3198] (rev 06)
I began searching the solution and unfortunately nothing works including this trick to add options on /etc/modprobe.d/alsa-base.conf
options snd-hda-intel dmic_detect=0
and include the blacklist for module snd_soc_skl on /etc/modprobe.d/blacklist.conf
blacklist snd_soc_skl
do a reboot but still no sound from speaker and got dummy output at pavucontrol.
I also try to determined the vid/pid from that lspci as :
options snd-hda-intel index=0 model=auto vid=8086 pid=3198
still got dummy output as well
but when I change the primary to PCH then HDMI :
options snd-hda-intel id=PCH,HDMI enable=0,1
there is some slight change on aplay -l output as these :
aplay -l

but unfortunately still no sound, the pavucontrol still shows dummy output.
I have ran out of idea for now, and i really hope, maybe someone who experienced something like this could help me. Can somebody help me please? Thank you very much in advance.
