Using the Digital Out on the Powermac G5

I’ve been running M-Audio Studiophile SP-5B near-field monitors for a while on a couple of different Macs. My B&W G3 was playing iTunes for several months through them and, periodically I used them with the TiBook as well. In both instances I was using the Xitel HiFi-Link Pro via USB and thought the performance was pretty good. The set up I used here was RCA out of the HiFi Link to a 1/4″ adapter to plug in to the M-Audios. There were a few issues but no real bugs plus noticibly better sound than using the headphone out jack.

With the recent purchase of a G5, and the availabity of the digital out port, along with a bug that would not let me route Garageband through the HiFi Link, I decieded to get a real DAC (digital/analog converter) to take the optical sound output and convert it for the best input on my SP-5Bs, XLR, baby! I picked up a M Audio Super DAC 2496 from Amazon and got it hooked up.

Shazam! There is a noticible difference in the quality even with iTunes but real CDs and DVDs are just killer! Two thumbs up!

I also use Detour to help route sound to different outputs. This worked great with the USB set up. I could pass system and non essential program sounds through the built-in output and route the good stuff through the SP-5Bs. On the new setup the digital out is counted as built-in audio so I can’t run system sounds through the little built-in speaker in the G5. The sounds come through the SP-5Bs. I can still route the system sounds to USB though so If I get a little USB speaker setup that may be the ticket.
Whatever, going with this digital out setup is too cool!

Did you get any more info on the bug? It’s really annoying.
