I’m not sure what the title has to do with your post. Is that an error message you got somewhere? I see devices listed? Audio issues can get complicated. The first step would be to check alsa, use amixer, and ensure nothing is muted, make sure you check the right device, and check your keyboard and ensure you’re not muted with your hardware. Check your journalctl -b for error messages as well.
Here are some resources to read up on too while waiting on additional ideas/help:

Know someone who had the same problem with the same laptop (255 g9), it worked with pipewire, and kernel version 6.1+.

If it isn’t detecting your sound card at startup you need to reset the hardware:

  1. shutdown
  2. unplug power from laptop
  3. hold power button for 10 seconds
  4. start pc

Apparently, if there are headphones plugged into the stereo jack it’s picked up at startup. But when you reboot without them plugged in, well then you have to go over the whole hw reset process again.

BTW, they were using Debian 12 with Gnome, it’s probable just a driver issue though, so the newer the kernel the better off you’ll be.
