Hi Vasily,

The issue is reproduced in our BDW NUC too.
I applied the "diagnose.patch" and check the dmesg, the cdclock received by
audio changes when issue happens:
in normal case, cdclock = 337.5MHz;
when issue happened, cdclock = 540MHz.

Could you please double check on your platform, through either intel_reg read
or dmesg, to see if we observed the same issue? Sorry I have no Lenovo Carbon
X1 gen3 laptop on my hand.
