Hello, I'll follow up with you guys probably tomorrow (but possibly as soon as later today). I've just been having an eventful holiday weekend.
As tomorrow is a normal weekday that I have off, I'll finally reach out to Lenovo again tomorrow myself. Doing a quick search, I don't think anyone has shared their Legion Slim 7 Gen 7 AMD alsa-info. Can someone do that? It's likely still the CSC3551, but it would be good to confirm. As for those ACPI messages... Looks like you have ACPI some stuff that isn't supported under Linux yet. It's a fairly new laptop, so that's to be expected. I don't really see that on my current laptop, but I do see it with my current desktop which I've had for under a month (Asus Crosshair x670 Extreme). The CCP messages means Linux can't utilize the AMD Crypto Co-Processor on your CPU. I've had this message for my current desktop as well as my previous (AMD 7950 and 5950 CPU's respectively). From my research, the motherboard vendor (both Asus in my case) need to fix the BIOS. Maybe it's a similar issue to what we're seeing with our laptops. While unfortunately, it hasn't really impacted me.
