No sound with Realtek ALC287

[GitHub issues - opened]

alsa-project/alsa-lib issue #76 was opened from BLuFeNiX:

I get no sound via the speakers of my Lenovo Legion 7i laptop, which alsamixer tells me is using a Realtek ALC287.

Here is my alsa-info.sh output: http://alsa-project.org/db/?f=4272343a3590cc08f192f98113dedfc0418afe52

I made sure to disable Auto-Mute in alsamixer, and turn all volume levels to maximum. In all cases, I get no sounds from the speakers (running speaker-test, playing music, etc.). I *am* able to get sound via headphones and HDMI (though I believe HDMI is via a different sound card).

I previously reported this here: https://bugzilla.kernel.org/show_bug.cgi?id=208555
but I received no response in almost 3 weeks, so I think maybe I have reported it to the wrong place.

Please let me know if I can provide any assistance or additional information.
