Did anyone test this?

I get this output:
Jul 20 16:20:32 surface kernel: rt5640 i2c-10EC5640:00: Device with ID register 0x6308 is not rt5640/39

With the early warning telling me it's probably not going through the
quirks, though the rest of the output makes me think otherwise.

After PulseAudio starts I get:
Jul 20 16:20:40 surface pulseaudio[1315]: [pulseaudio] module-alsa-card.c: Failed to find a working profile.

Jul 20 16:20:40 surface kernel:  Audio Port: ASoC: no backend DAIs enabled for Audio Port
[and plenty more of that last line]

$ journalctl -b | grep "Audio Port: ASoC: no backend DAIs enabled for Audio Port" | wc -l
1802

Ideas?
