I have 8086:9d71 on a Xiaomi Redmi laptop and it dose cause some sides. If you simply disable the SST driver and fallback to the legacy hda driver, despite the various NID pin errors on different machines, the digital microphone won't work at all. Maybe the only solution to this is to 1)looking forward to sof firmware support, which is not much possible since the hardware(8086:9d71) we're using is based on kbl, or 2) get the proper SST driver for this platform working, it's the only firmware that supports both dmic and sound output.
