Comment # 7 on bug 916577 from Takashi Iwai

Hm, I see no obvious difference between 3.18 and 3.19 after resume.  Both look
as if the device gets restored properly.

Could you run vlc (or mplayer or whatever a simple program to show the stream)
with strace -f?
   strace -f -o /tmp/strace.out vlc ....

then attach the output file (better to compress it first).

BTW, the first queation is still unanswered.  Does suspend-to-RAM work?
