It seems the default in Debian 12 is now pipewire. I have no sound on this new laptop. I am looking for the easiest solution (with pipewire or pulseaudio) to restore basic sound management. AlsaMixer tells me I have a Realtek AC245 chip.

I've tried speaker-test -Dhw:0,B -c2 -r48000 -f S16_LE with B in 0,3,4,5,31 as suggested from devices above, with and without headphones. Note that I can record sound, using sof-hda-dsp hw:1,6 using e.g. Audacity. But Audacity stalls if I select output with sof.
The part that seems to me relevant from usr/sbin/alsa-info:

"No sound server found"? Although:

/lib/firmware/intel/sof/*- do you have it? See thesofproject.github.io/latest/getting_started/intel_debug/… for more context.HP-HPElitex360104014inchG102_in_1Notebookmeans "HP Elite x360 1040 G10 2-in-1 Notebook", then you have the latest-generation chipset and not Skylake at all. It might be that the default kernel of Debian 12 is simply too old for it. Debian Backports seems to currently offer a 6.7.x series kernel for Debian 12; you might have better luck with that kernel version.sudo update-pciidsto ensure your PCI ID catalog is up to date, then runlspci -nnand add the output to your original post using code formatting. Even if nobody has yet added the appropriate text labels to the database, the vendor/product codes[XXXX:YYYY]should be recognizable by comparing to chipset datasheets if necessary.
