I cannot say for certain what is the exact cause of the problem because I am just not there to troubleshoot... but in my Logitech Z5500 Digital, the clipping sound used to occur when the chipsets inside get really hot! I swear, it used to be like heating a pan on a stove. I would recommend this method to determine if it is overheating:
1) Take a note of the time in-between the clicks you hear.
2) Once your certain of the time between clicks and that they are consistent, use your mouth to blow into the vents at the back of the control pod (and for pete's sake... NO SPITTLE.. lololol, seriously!). Give it a good blow outuntil the temperature of the air coming out feels noticeably lower than on the first attempt.
3) If you find the air coming out is hot enough for you to be concerned that is usually a good sign that it might be overheating.
4) Sit back again and listen back for the "clicks"... If they are coming at the same rate, then it most probably isn't overheating. If however the time between the clicks gets longer, or if there aren't even any more clicks, then the pod is overheating.
I would also like to state that sometimes it can be the software you are running that is causing the clicks. FOr example I get clicks when I watch TV through my MSI TVAnywhere Plus on Vista x64.
It may be time to look at an RMA if the problem is getting ridiculous. No speakers should give clicks like that. It is either the audio source or the control unit itself.

With me, the crackling / hissing noise occures when i turn on the Matrix option on the Logitech X-540.
You should use the speaker-separation system from your soundcard instead of the Matrix option.
With Creative it is called CMSS-3D. With realtek it is called "Fill Speakers" ore something.
Just check if the hissing noise only occures when you enable the Matrix option, if so, that's your clue!
