I tested with fedora 33, 34 and Ubuntu 21.04. Only the high frequency speakers at the laptop bottom are working, while the speakers above the keyboard are off. Here is a link to the laptop https://www.lenovo.com/de/de/laptops/yoga/yoga-slim-series/Yoga-Slim-7-15IIL05/p/88YGS701403
In Microsoft Windows 10 everything is fine.
In Ubuntu 21.04 i can at least change the bass speaker volume in alsamixer, but it is changing hardware master volume instead of hardware bass speaker volume.
In Feodra 33 and 34 i can not even change the bass speaker volume in alsamixer
You can immiediatly hear, that the bass speaker above the keyboard is off
