Jitter during music play while accessing harddrive?

After having used my computer for more then a year, I accidentally noticed some disturbing sounds while playing music with my 'normal' music player (MediaMonkey, which also keeps track of all music on my harddisk). This only happens after my total memory 'has been converted to standby-memory'.
I know a lot has been said/asked about the internals of Windows 7 memory management, and I guess this is one of the cases where I also have to raise a question.
I understand the reason to have memory on standby, easy to grab a chunk :).
But I don't get any insight in what happens when my 32GB is fully converted, the audio I play needs some data from the disc, any played music (whether .flac or .mp3 don't care), will be release and reused if needed. At first, I didn't even hear any disturbance, so I guess it is something that is caused by newer software/management/whatever.

After a restart, I can wait until the memory is full on standby, and the same thing happens. This is annoying to say the least. It looks like something is disturbing (on a higher priority task) music playback, and that task takes too long time (millisecond level). The jitter/disturbance is audible like:
slowing down the beat for a second or so.
annoying 'scratches' inside playback (which is not in the recording)
small repeating patch inside playback

In case you would say: why not move over to another Media Player: I did, was my first idea, but it doesn't help, the result is the same with Windows Media Player (which is not my first choice, but does the job very well indeed).

What I have tried to do thus far (but without any noticable results):
Pagefil.sys
Since 32GB memory should be enough, I would like to run without additional swapping memory, so I
started running without it. Went OK for a while (I think).
Had pagefile.sys on SSD: same problem
Had pagefile.sys on HDD: same problem
Had windows manage pagefil.sys: same problem
Had no pagefile.sys: same problem
Updated:
Realtek audio drivers
Nvidia video drivers
Internet port drivers
MediaMonkey

Tip for getting memory converted to standby: copy some huge files.


Suggestions are really really welcome !
