I can't reproduce this problem on a similar configuration of debian
testing amd64, so I'm going to wager a guess that this may be
hardware-specific. We may need to know more information about Mira's

For my part, can't reproduce the problem with an Intel 82801JI
(ICH10R)  HD Audio chipset from the onboard sound of an Asus P6T
Deluxe motherboard (based on Intel X58 chipset). My manual test script
is as follows:

1. Start Firefox or Iceweasel
2. Play audio through Adobe Flash *and* through the built-in support
for e.g. VP8 or Ogg/Vorbis and ensure that it works correctly, then
stop the audio (didn't test the case where you suspend *while* audio
is playing)
3. Suspend to RAM
4. Resume back from Suspend to RAM
5. Play more audio and ensure that it works correctly

By "correctly" I mean, it doesn't skip or pop after testing it for 5
or 10 seconds. Doesn't mean that it's 100% reliable or as low-latency
as it should be :P Not sure what other ill effects suspend to RAM
might have if I were to rapidly suspend and resume dozens of times...
did not test that.

Lastly: one thing I always suggest to those who have problems with
PulseAudio is, try killing PA and playing audio through a plain ALSA
application. Try something like `aplay` or `gst-launch-0.10` with alsa
hw:0 device or similar, to avoid going through PA. If you can
reproduce the defect with pure ALSA without pulseaudio involved,
99.9999% chance it's not a PA bug, but an alsa-lib or alsa-kernel bug.
That should be reported upstream IMHO, esp. if you're using the latest
stable kernel or newer.
