http://alsa-project.org/db/?f=27a16819ac2dd8b01ba4e840d001e8f6fa34f222 alsa info output attached. kernel 6.7-rc8. The sound output and mic input works fine. Mute and Micmute LEDs can not work. Not sure if it's GPIO based LEDs.
This model doesn't use thinkpad-acpi it seems like. Assuming that it has some ACPI interface for changing the LEDs perhaps it needs to have the LED handling ported from thinkpad-acpi into ideapad-laptop. I'd suggest checking with Lenovo.
