Updates:
Both of the 2021 Legion's (the AMD based Legion 7 16ACHg6 and the Intel based Legion 7i 16ITHg6) have sound issues under Linux.
Sound doesn't work at all under the AMD based 16ACHg6, and sound partially works under the Intel based 16ITHg6.
In the case of the Intel based 16ITHg6, sound works until you suspend to memory. Plugging in and removing headphones doesn't affect speaker output (so far). Probably the BIOS initializes the amp at book, but not at resume. For now, I'm using hibernate instead of suspending to memory.
Both laptops appear to have Cirrus Logic CS35L51 amplifier chips. There is presently no Linux support for this chip, and no publicly available datasheets as of yet. However, a driver is currently in the works for the CS35L41:

So maybe we'll eventually see support for the CS35L51.
This means the audio output issues with the 2021 Legion lines are unrelated to this bug or at least the ongoing work that has occurred under this bug. I will eventually update the document to reflect the state of audio are the 2021 Legion's and what we present know here:

Huge thanks to Marcus Aram who discovered the amplifier chip and its model and has been working towards getting this resolved.
