@Christoph and @Lakshmi 

Thanks for figuring out the root cause of the bug. 
The patch "drm/i915/audio: set proper N/M in modeset" is trying to setup the
M/N manually because there may be some bugs if we use HW automatically
calculated value on some specific platforms.

Like Keqiao's previous comments, we couldn't reproduce this bug at that time.
Maybe the M/N is not accurate or maybe the new platforms have new requirement
to set the M/N. I got the final M/N value from other team when I made this
patch. I will check whether the value is correct or not.

As I didn't work on legacy HD-audio driver for a long time, I don't have proper
platforms to test now. I need to find a proper platform to reproduce this bug
firstly.
