How to reset / reconfigure sound drivers

Hello,

This may be a strange and complex problem but I still hope someone can help me.
I own a iMac with OSX 10.6.2 on which I have connected a USB Audio interface 'Yamaha Audiogram 3'. I also use this device for my sound output through external speakers. I haven't had any problems with this since I installed the audio interface.
But today I installed a program called 'Guitar Pro 5', which radically seemed to have adjusted things in my sound driver setup or whatever it is called. Because ever since that moment every sound I hear through my audio interface and my external speakers contains a low and soft noise which is influenced by the sound played, often peaking as cracks, as if the speakers are broken (but they aren't).
I have already consulted the Apple Care but all their suggestions didn't solve the problem.
After this I also tried reinstalling the driver required for the Yamaha Audiogram 3, but to no avail.

I figured the problem might have its roots in the sound driver configuration, but all I can configure right now is the balance, the volume and the choice of which speakers to use. I think I need to dig deeper than that, and find out why my sound is so wrecked.
Are there ways to do this?
And if the problem can be solved in another way, please let me know!

Any help is greatly appreciated.

iMac, Mac OS X (10.6.2)

Hi Twilight31 & welcome to discussions...

In order to get your audio working, you need to go to System Preferences > Hardware > Sound and select the sound input/output hardware that you want to use.

But you also may have to run the Audio MIDI Setup utility. Go to Applications/Utilities and run 'Audio MIDI Setup' - confirm the configuration/settings there match your expectations, etc.

The use of two locations for setting audio configurations is confusing for many users.
