lspci command | grep audio shows nothing
Why do you think there is no sound? is it a driver issue? If yes, how to install the driver?

apt-get install alsa alsa-lib alsa-base alsa-util libdssialsacompat0
We go into alsamixer, we raise the sliders up, we check.

First, to check which cards have been initialized in the kernel, you need to issue the "arecord -l" command, it will be something like this:

[email protected]:~# arecord -l
**** List of CAPTURE Hardware Devices ****
Home directory /home/xxx not ours.
card 0: PCH [HDA Intel PCH], device 0: ALC892 Analog [ALC892 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 2: ALC892 Analog [ALC892 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: S0000 [SC580, Audio Capture #00.00], device 0: PCM #00 [PCM #00]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 2: S0100 [SC580, Audio Capture #01.00], device 0: PCM #01 [PCM #01]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 3: S0200 [SC580, Audio Capture #02.00], device 0: PCM #02 [PCM #02]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 4: S0300 [SC580, Audio Capture #03.00], device 0: PCM #03 [PCM #03]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

The second is to look in the BIOS, maybe the card is simply prohibited.
Third, run alsamixer and move the sliders.
Fourth - if there is a graphics, then look at pulseaudio, access rights to audio devices, and so on.
If there are no devices via arecord, then look in the direction of the drivers...
If there are devices, then at least they work, but the sound may simply be routed to the wrong place by the audio daemon, usually pulseaudio, but sometimes jack-audio and oss!
Well, check that just the sound goes through the desired card:
Well, here's a link to everyone - en.wikibooks.org/wiki/Configuring_Sound_on_Linux/H...

$ sudo aplay -l
aplay: device_list:274: no soundcards found...

add the firmware-sof-signed package:
$ sudo apt install firmware-sof-signed
add source pack "non-free" -

# --- Debian 11 --- #

deb http://deb.debian.org/debian bullseye main contrib non-free

Examination..

$ inxi -F

Audio:     Device-1: Intel Tiger Lake-LP Smart Sound Audio driver: sof-audio-pci 
           Sound Server: ALSA v: k5.10.0-9-amd64

reboot.
And it should work
