I don't do any audio, but I had used a g5 with 8 channels on a edirol FA102 (something like that) firewire interface. everything seemed to work fine...
Did you look at the audio settings in the pull-down menu? you should be able to select applicable sound devices. I have noticed that I sometimes have to change the number of in channels to get all the out channels to work, but I can't remember if this was just on PC hardware or on Macs as well.
Anyhow you can now do almost everything in flags from the GUI interface, give it a try and see if you can get it working.
I have no idea about optimizing for latency...

Hello,
we're trying to set up a system for a concert, which is happening on next Tuesday (very tight schedule).
The system is G5, osX 10.4 (dual 2.7G), Digi 002 firewire (it works, was tested with max-msp), running PD official 0.39-1.
I'm a bit confused, because I can't find any definitive documentation about OsX. I mean, in the manual the startup flags are clearly defined for windows and linux, but I don't know exactly what to write on the G5. Until now (besides loading libraries) we wrote the parameters -audiodev 2 , which selects the Digi as the audio interface (the other one is the standard Mac soundcard). Funnily -channels 8 didn't do nothing, they remained at 2. But then on the audio test patch it isn't possible to get any sound. On a tryout basis we went through -asio and -pa, but nothing changed. So I guess pd can identify the card, but it doesn't communicate with it. And as I can't find a complete list of osX flags, I don't know which might be missing.
Has anyone any exprience with this environment? We're starting to sweat, since the concert is in a few days and it's proving to be harder to make pd work.
Thanks,
