I get no sound via the speakers of my Lenovo Legion 7i laptop, which alsamixer tells me is using a Realtek ALC287.
I have tried various Linux distros and kernel combinations, including Ubuntu 16.04, 18.04, and 20.04, with both the default and mainline kernels (5.7.x & 5.8.x), and Manjaro with 5.6.x, 5.7.x and 5.8.x kernels.
In each case, 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).
Also, I can see that there is some kind of sound activity occurring when I look at pavucontrol (the reddish-orange bar that indicates a sound is playing), but there is no actual sound produced from the speakers.
My alsa-info.sh results (from Manjaro on 5.6.15) are here:

I am happy to run the script again (or any other tool) from a different distro/kernel combination, please just let me know what would be helpful.
