Hi all,

It only happens with 48KHz.

I'm working on drm-intel-nightly, 3.15.0-rc3. I will test on the latest
drm-intel-nightly later.

Today I find another interesting clue: WHen there is no sound, if I reload the
audio driver, the sound comes back.

Based on all the symptom, I think this may be the asynchronous issue between
audio driver and video driver. As other monitor is OK, is there any possibility
that gfx driver delays while audio driver setup with the wrong information for
the special monitor.

Thanks,
Libin
