Sound problems on Intel iMac

[celliott]

I have a 17" Intel iMac C2D, 2GHz, running Leopard, 2GB ram and all current hardware updates. Since it's at my office, I haven't done much with audio. Lately I've started listening to music through iTunes. The problem? At low volume levels the sound cuts out. It sounds like someone using a voice activated microphone. I did some further checking and it happens when playing movies also. It seems like any low volume audio is dropped.

I'm not a novice and have used Macs since 1986. I currently have two iMacs and the family has 3 MacBooks. The same audio I tried at my office (and movies) play just fine on my 20"iMac at home.

Any thoughts? Is there a known problem or is this isolated? Or maybe I'm missing something.
Thanks

If you're using USB for audio, there may be a difference between the two USB ports.

not doing anything with the USB ports- this is straight audio coming out of the speakers (or not coming out, as the case may be)

celliott What type of speakers/amp/cables?
The first thing I suspect is a bad cable.

Nothing added, straight out of the iMac speakers.

Fritz- thanks, I may look into the clean install.

Sounds like a hardware problem.
Try logging in as a different user first though.
