Hi! I have the same problem and want to add some information.

The following fix works (temporarily):

https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/202089/comments/19

This seems to indicate a kernel bug.

The suggested fix worked for me:

>> I was able to fix the problem by adding the following line to
>> /etc/modprobe.d/alsa-base :

>> options snd-hda-intel model=6stack-dig

Now my computer suspends/resumes properly.

>> Also, can you please double-check that *every* sound device works
with that model?

"model=auto" should work with every sound device, but there's a bug that
prevents it from working on resume.

See this document:
http://bugs.archlinux.org/task/10495

"model=6stack-dig" should NOT work with every sound device. "model=auto"
is the default, but, like I said, it's broken.

Here's the list of values for the model parameter:

Configuration.txt#769

As you can see, it's quite an extensive list, and sadly it's very
hardware specific. So there's really no generic fix that the Ubuntu
developers can deliver. The only solution appears to be an updated
kernel with a fixed snd-hda-intel module.
