Random sound glitches in SC4 Mac

[DavidB_ 83]

Hi all,

Recently, I have been experiencing a number or random sound glitches in SimCity 4, including pops, buzzes and other random noises, although they do not occur very regularly. I don't know whether this is because of my computer or because of any plugins, but the noises only started when I transferred my game account across to my current computer via Migration Assistant (computer details below), and installed the NAM (my only plugin for a while). The noises have been occurring ever since, so if anybody has a suggestion to what may be causing this, or how to fix the problem, it would be gladly appreciated. And if anyone thinks removing my plugins temporarily would help, then I will gladly try that out.

Thanks in advance for your help, and please ask if you would like to know anything more. However, I don't know if it would be possible to record the sounds!

Computer:

Power Mac G5 (June 2003) - Dual 2.0GHZ1.5GB RAM

250GB Hard Drive

Playing SimCity 4 on dedicated account, logging out of all others. NAM, all optional components (NWM, RHW, HSRP, RAM and SAM) as well as other plugins installed.

UPDATE #1: Similar noise issues have also occurred within UDI, but I am not certain.

UPDATE #2: The glitches don't seem to be occurring much any more, they did appear more often when working with Puzzle Pieces/RHW however.
