Comment # 15 on bug 964621 from Takashi Iwai

I prepared a test KMP in OBS home:tiwai:bnc964621 repo.  After installing it,
you should have
   /sys/module/snd_hda_codec_via/parameters/delay1
and
  /sys/module/snd_hda_codec_via/parameters/delay2
files.  These are delays to be put at resume.  As default, both are 10 ms.

At first, try as is, whether it works.  It has an extra delay after init, so
this might help already.  If this doesn't work, try to increase the values. 
You can change it like:
  echo -n 100 > /sys/module/snd_hda_codec_via/parameters/delay1
