Today I installed my new Fireface UFX on a Mac Pro running 10.6.8, with DP 7.23 as the main DAW (I also use Logic).  Downloaded and installed the latest drivers and firmware.  The device shows up in the audio-midi panel, the midi works, etc.  For basic testing, I ran the outs of an external midi synth (Roland XV-5080) into analog 1-2 of the UFX; I hooked up my monitor speakers to analog outputs 1-2 (main).  The synth is receiving midi signal from the UFX, and its output shows up in Total Mix meter on input analog 1-2.

Here's where it gets weird.  Analog 1-2 (along with every other input) is routed to the Main (analog 1-2) out (according to the Matrix view).  It shows up visually in the hardware outputs (analog 3-4, 5-6, 7-8), but not at the Mix output (analog 1-2).  There is only one exception: Analog 3-4 shows up at the Mix as well as analog 3-4 out.  So I can hear anything in the software instruments I set to analog 3-4 out, but not to anything else (I'm just talking analog here, haven't hooked up the AES, etc. yet).

To make things stranger, I can't hear any audio output from the Mac at all (like iTunes, etc.) when the UFX is selected as the main sound output device.  This wasn't the case when I used Apogee Symphony, whose 32-PCI card is no longer compatible with 10.6.8 and later OS.

Well, I'm probably missing something basic, but I thought I would query the list and see if I could find out what it is.  Any advice would be greatly appreciated. Thank you.
