Sorry about the delay! Thanks for the update. Latest snapshot (kernel 6.8.1, newer version than the rc you suggested before) still has the same behavior. I will check i2cdetect and try some quirks. Is it safe to switch between those different models of speaker quirks while my system is still running with sysctl? Also, what should I be looking for when testing these quirks? That the speakers sound identical to Windows 11? Or that they just sound good subjectively? No response on the Lenovo forum post, maybe I could ping that again too.
