This problem seems to affect HP SPECTRE x360 15-eb0675ng, too. This device has a Realtek ALC285 (sof-hda-dsp) sound card. Audio is working via line/headphone output, only. While a headphone is not connected, PulseAudio recognizes that nothing is plugged in, and when it's connected, it says headphone output. Alsamixer also confirms muting and unmuting of the integrated speakers, as well.
Sound is working perfect via line/headphone out, but speakers don't work.

We are sure that an integrated mini amp behind the sound card has to be triggered via special registers, too. We can confirm that it works under Windows, same thing as mentioned above.

You may want to apply your linux-5.13-legion-sound-0.0.11-002.patch for this device, as well. The diff looks like it would only take effect on the special Lenovo laptop, so I thought it would be a good idea to inform you about it. Maybe the patch would work 1:1 on the HP laptop, too.

If you need more information, I would like to support you as best as I can.
