Hi Dominik,

Thanks for reporting, yes, this is Keyon(Yang Jie) here, we do have 
several other Broadwell comercial platforms in the market, adding Curtis 
from Google in case they may hit similar issue once upgrading to the 
latest kernel.

 From your description above, it looks the ucm and pulseaudio is 
involved, can you help do a quick try if using aplay directly will hit 
the same issue?

Thanks,
~Keyon
