Ultralite Mk3 To Mac Pro - No Sound Options

[rostasi]

Hi,

First time post. I hope someone can help.

I have a digital Stanton turntable S/PDIF'd to an Ultralite mk3
and out to a 8-Core Mac Pro. When I check my sound Preferences on
the Mac, it shows that it's receiving sound from the turntable
(the imput level "meter" is animated with the sound from the LP)
and my output is set to "Line Out" (the way I've always listened to
things on my Mac - and that still outputs, say, iTunes).

Here are three screenshots if this helps:







I've tried playing around with different settings in the MOTU Audio setup,
but even tho the graphic meter (in Mac Preferences)
shows that it's receiving sound, I'm still unable to get anything
out of the external speakers with this MOTU setup
(tho I can still listen to iTunes, so it's not a speaker problem).
I opened up Audio Hijack Pro and a simple audio editor
and the sound never reaches there either, so I'm stumped

Also, headphones hooked directly to the UltraLite deliver sound.

Do I just have my settings wrong somehow in the MOTU audio setup window?
It shouldn't be such a head-scratcher, but am I missing something obvious here?

thanks,

Rod
