Traveler Troubles, Quad G5, No audio from Traveler on Quad G5 Options

[GitGeezer]

For those of you with (or considering) a MOTU Traveler firewire interface:

Very slow (if any) response from MOTU on the following issue, so I thought I'd find out if the forum had some comments...

Audio output from the Traveler is never available after the first cold boot. Sometimes it will return after a restart. Mac audio software (iTunes, iPod, Quicktime) also behaves erratically after attempting to use the Traveler interface, but is usually available even when audio doesn't work from the applications listed below. Attempting to configure speakers from Audio MIDI Setup produces nothing (no pink noise) but a few soft clicks. MIDI is being received by applications.

My system:

Interface: MOTU Traveler, external AC powered
System: Mac Quad G5, 4Gig memory, 200Gig available disk space
OS: OS X 10.4.2
Core Audio Framework version 3.0.1

Traveler firmware: 1.05, bootloader 1.0
Last installer used: fw_1.3.0
Drivers: 1.2.5
Cuemix: 1.5

Audio apps: Logic Pro 7.1.1, Absynth 3, Reaktor 5.2, Sibelius 3, Garritan Personal Orchestra


I have repaired permissions many times. I've installed the most current drivers (see above) from the MOTO support website. The Traveler is set as the default input and output device in Audio MIDI Setup. I would prefer not to upgrade to OS X 10.4.3 yet (and definitely not to 10.4.4), but if necessary I will.

Thanks in advance for any suggestions,
GitGeezer

Have you trashed the system caches? The audio/MIDI prefs? Temp files?

For the caches, temps files, use OnyX

go to maintenance, run top half of options (don't mess with classic if you don't use it/have it installed)
go to cleaning, check almost all in the bottom 2/3 save the items on the right but do check in these the police cache.
(no OS/finder/whatever should have no dead beats left in under the hood files which can be expended -recreated by the OS anyway)

and right after that, shut down, unplug mains and peripherals, wait 30s, replug, restart.
(now, ports should be reinitialized)

redo your audio MIDI set up.
If it's not working after another restart, it's 99% likely the driver or the driver/OS/hardware combination has a problem. As there's been some issues on the Quads (acknowledged by Apple) , i'd check the support pages at Apple too!
