Pathetic. Well I have the lynx card installed in my G5, the machine booted up fine, installed the drivers on the disk that came with the card. Rebooted the machine. After installing the custom cable, I took every care to make sure everything was brought up properly. Made what I thought were the correct settings in the Audio Midi setup of OS X and the "sound" preferences setup. Turned on the Bryston BDA-1, got a clear green lock on the signal from the sound card plus a sample rate, all green lights. Unmuted the Bryston. NOTHING. Maybe a volume issue; scanned the volume up, definitely not a volume issue on the preamp. The bryston was playing beautiful music through a USB port on the G5 an hour ago. No changes in any other settings or cables. When I load up Lynx's little mixer it shows me that signal is passing through and bouncing around equalizer style. WHY NO SOUND????
No worries, we'll get it figured out.
Is the Lynx set as your default audio output device?

Yes. Audio midi setup - Default output is set to 1:AES-16. I am a real newbie to this and I am noticing there are obviously two ports on the rear of the card. My custom cable from redco has only one plug for the card correct? Does it matter which output side of the card you use?
I can send you snapshots of the settings in the OS if that would speed things along. Thanks for replying and helping me with this so quickly.
One thing on the audio midi settings -
On the RIGHT side of the panel I have default output set to (1:AES16) (and then as SYSTEM output presumably for system sound effects? I've set to build in audio.
Under that for Audio Output I have Source Digital Out and then the correct sampling rate info.
However to the left I have Audio Input which I've left at their default settings and above that are Properties for:....Not sure how those are supposed to be set. There is a pulldown for the 1AES16
Here are some screen shots of the midi setup screen and the obviously locked on the signal Bryston. Honestly there are no troubles further upstream of the Bryston. The same connections to the preamp, amps, everything on, muting preamp on and off, but no music.

Set default sound on "sound' preferences output to the card. One questions - since the dac is locking on a signal and showing the sampling rate, does that automatically mean that its getting the proper signal from the card and the mac? Would it then mean that there's maybe a switching problem in the Bryston if the USB input works but the AES/EBU doesn't seem to work on this particular sample of the Bryston?
Can you head over to the "Listening Room" so we can chat in realtime? Here is the link http://www.computeraudiophile.com/The-Listening-Room

What are you wearing?
Oh wait, are we in the chat room yet?

Thanks to Chris - this puzzle was solved. Meltdown averted. Thanks!
Well?? Please tell us what the problem/solution was? That's the setup I eventually want to get so am interested in any problems.
Thanks,
Chris
Interim setup: Battery driven Macbook Pro with 4G Ram, running PM ->Tact 2.2 (with no processing from the Tact), -> Bryston 78-ST monoblocks, or Canary CA-339 300B monoblocks -> Tidal Audio Piano's.
A work in progress...
If you must know I had the cable hooked up to the output B on the card rather than output A (I think that's right - anyway one of the ports on the card is for "record" and the other is for "play"). Once I got that straightened out that was pretty much it. :o
Thank You for the info. Good to know!
