The BIOS points to a combination of RT1316 (SDCA) and RT1308 (non-SDCA) and the kernel reports bus clashes on link2.
This could be a mistake with just a mono amp on link1.
Let's try this theory.

Fixes: #3161

We don't have a configuration for a single amp on link1.

This device is based on SDCA codecs but with a single amplifier
instead of two.

Sorry, please forget my previous comment. That is alphabet l, not number 1. It must be sdw link. I need a new glasses.
