iMac audio issues

I have an iMac (model right before the first dual core) and have been running through an M-Audio Audiophile firewire eternal DAC for about four years. During this time, the internal iMac speakers by and large didn't work when selected in system preferences.

I now have an HRT DAC I would like to compare to the M-Audio DAC, and I can't get a signal to it. The HRT shows up in the audio preference list, but the only sound I can get through the iMac to the HRT is sound effects. I can also get sound effects when the iMac internal speakers are chosen.

I have disconnected the M-Audio and deleted all related software with no improvement. I think I have a software issue that needs to be repaired.

Anyone else deal with iMac audio issues.

A different problem but my iMac with HRT II+ connected, displays a message
usb device is drawing to much power and the usb is disabled or a dimming and erratic desktop that can not be used is encountered. HRT"s support web page is not working, an HRT distributor is looking into it. Has anyone else heard of this occuring?

Yep, usb direct to the back of iMac (27" 3.06GHz OS X 10.6.4) it worked OK
initially. I have tried a different usb cable. and some basic diagnostics.
A powered usb hub does not work, Leopard does not see the HRT when attached to a hub apparently.

Roscoeiii,

Do you use a Mac? Maybe I should try again before I return the powered hub.
