I've written MOTU about this, they say they can't reproduce it- perhaps somebody here can?

Any application I'm running in Leopard that has a chime or sound at the end of an operation- so far, including Toast 8, Jam 6, Peak 5/6, First Class mail & Entourage 2004 (the latter 2 after sending mail, the first 3 upon completion of burning a disc)- "unexpectedly quits" when that sound is generated. (There are no problems playing normal audio through my MOTU 2408 mkIII, only when these "system sounds" are generated.) This is partially alleviated by routing system alerts through built-in audio, which I would do anyway, but it's not 100%.

In Jam, this also happens when playing and then changing the track you are playing by clicking on it; in Toast 8, you can disable the "Bing" in preferences as a workaround, but it will crash if you try to playback from the Custom Crossfade window.

This is on a clean partition, an "erase and install" of Leopard, with a new user profile (no migration assistant from my Tiger system, which remains my main setup). I tested before and after updating Leopard to 10.5.2 and also before and after updating Quicktime. Permissions have been fixed (though there were none to fix). I have also upgraded to 10.5.3 (using the combo updater) and there is no change.

I'm on a G5 Dual 2GHz (June 2004), 5GB RAM, 10.5.3, Quicktime 7.4.1, and the only 3rd party audio driver is for the MOTU PCI-424 card. Again: Minimal, fresh, clean install.

It gets even more specific: the problem only happens when bank C of the 2408III is set to spdif AND one of the other banks is active. The workaround then is to disable banks A and B, but that means I can't use those inputs when recording in Leopard (without constant switching setups back and forth).

Anybody got an idea?

Thanks-

Anyone else having this at all? Later updates of Leopard and Quicktime have not resolved this.

I know I'm not the only one with this problem, there's been a thread over at Macintouch where it's cropped up.

Gary, your sig still shows OS 10.4.11 so I almost missed this suggestion: What about bumping up to 10.5.4 and seeing if that does anything? It's been out a while. I've installed it on my G5 dual 2.3 and it's working okay.

Nice catch James, but the problem only occurs in Leopard, as noted above. 10.4.11 is still in my sig because that's what I use everyday to actually get work done until this and other issues I have in Leopard (like not being able to use my Radikal over USB) are resolved.

With this and other problems I have that others don't seem to be able to replicate, I'm really starting to think it's my G5. Unfortunately, for me to update everything properly on a new Mac Pro is out of my budget- and the thought of how disappointed I'd be if I spent money for the upgrade and it didn't solve my problem!

Right... I understand, but you listed 10.5.3 as the Leopard version you are using, and what I was saying is that there is a 10.5.4 version that has been released and you might try to see if the newest version of Leopard helps.

Sorry, looking at my previous posts I see I was not clear about that. Yes, I have updated to 10.5.4 and the problem remains.

You should definitely report this to MOTU.... sounds like it could be a bug that they might be able to track down.

Been through a very laborious troubleshooting set with MOTU support (through TechLinks), as stated at the very top. The circumstances to reproduce are very specific, but they said they can't reproduce it and have let the matter drop )ignorning my siggestions that maybe I have a hardware problem).

I'd really like to know if anybody else can reproduce this.

The only problem like this is in Adobe After Effects CS3. With Leopard and my Mac Pro, anytime I would scrub audio or when it would finish rendering a composition and play the chime sound, After Effects would unexpectedly quit. At first I thought it was a leopard/intel issue (on my old G5 it would work fine), but it turned out I had audio in After Effects routed through my 828 mk I... When I switched it to the mac's internal audio output, everything worked fine. I don't have any problems like this in Toast 8 (although it still won't burn DVD+R Dual Layer discs, even though the G5 does it fine: identical burner and all)...

FWIW, this problem does NOT occur since I moved to my Mac Pro and upgraded to the PCIe-424 card.
