Guys, don't spam me (e-mail).

I don't have the detailed information about your hardware and it seems that the hardware vendors are using the amplifier chips for the integrated speakers on recent hardware which must be initialized, too. The linux support depends on the BIOS initialization (if any) at the moment.

The HDA codec setup in first comments for Legion 7i looks fine, but Realtek use many hidden (undocumented) registers to set some configuration parameters and may be some other chips (amplifiers) behind.

Contact Lenovo, if you can, for help (BIOS - Linux support). They are supporting more the non-gaming hardware in Linux (ThinkPad/ThinkStation series).

Also, adding David Ober from Lenovo to Cc.
