That seems like a known issue already tracked at
https://github.com/thesofproject/linux/issues/3248

There's a set of devices based on the ES8316/36 I2S audio codec which
needs dedicated quirks. In the existing reports the Huawei Matebook D15
is listed as using that codec.

The latest experimental code we have is here:
https://github.com/thesofproject/linux/pull/3107/commits

If confirmed, can we track this on GitHub so that all results for this
sort of devices are collected in one place? Thanks!
