It seems the bass speakers do not work in the latest Tumbleweed KDE snapshot on
the Lenovo Slim 7 16" AMD, 16ARH7, 82UX0001US (and this same model is called
Yoga outside the United States). This issue appears to be similar to that of
the wide range of recently released laptops that have the CS35L41 and TAS2781
amps, however I cannot find that hardware listed in any of my logs or online
spec sheets for this laptop. The closest I can find is that is has a Realtek
ALC3287 codec.

Also, the keyboard brightness keys do not work. It seems the internal display's
brightness value is bugged and shows up as a huge number in brightnessctl (and
other tools) rather than something within the expected range.

I can provide any logs that would be helpful. I hope this is an appropriate
place to report these issues. Thanks!
