Crackles with Soundsticks in Panther
Is anybody else getting crackling from their USBAudio devices when playing audio and also doing something that my spike processor usage like launching apps? It's really annoying and it never happened in Jaguar and earlier.
This isn't really a support question because I don't think it can be fixed without a software update that doesn't exist yet.

I *did* experience it under Jaguar, but it appears to be much worse under Panther and I notice it when I am making heavy use of the internet rather than processer usage.
:shrug:
The experience with my Rev A Ti 500, however, has not been problem free. Under Jaguar (various versions) I have experienced sound loss during heavy airport (streaming iTunes) or CPU load (Diablo 2 slaughterfest). I haven't played with the combo under Panther. The problem might have existed with Cheetah too, I don't remember.
The G5 obviously has much more bandwidth and CPU cycles to spare and I'm sure that is why it is happier. My question is, how do the Soundsticks-era machines fare? If my Ti has issues, what about 350 MHz iMac DVs and 400 MHz cubes?
Like i said its just a thought.

Just a though but have you tried changing your USB devices around on different ports? Do you have a powered hub that you could plug some into?
Both devices I'm having problems with are powered externally. My MX700 has an AC adapter, and the speakers are obviously powered. Why should I need to follow these suggestions when they worked flawlessly with the previous version of OS X?
It's the worst when I try to play sounds while contennt indexing or doing a massive "grep -r" ... At that point, sometimes the pointer just stops altogether and I have to hot-plug my mouse's USB connector again.
Some people are having problems with USB kernel panics on dual boots with jag and panther and upgrading with usb overdrive installed. have you tried a clean install?
I have the same mouse as you which is plugged in me ADC monitor, i've just switched it to the keyboard and it stopped working. how usb got popular is beyond me.

Cleaaaan install. I didn't even archive and install on this machine.

Ah, it's worst than I thought. It's not just USBAudio, it's just flaky USB in general. I just tried saving the new In America trailer from the Apple website, and not only did my sound crackle, my mouse pointer froze and jumped.
what are you saving your movie to? are you using a USB HD or zip drive?

Doesn't USB have to be moderated by the CPU and that's one of the reasons that firewire is superior? Maybe your problem is symptomatic of what happens to USB under heavy load.
I can't speak for the other guy/gal, but all I was doing was listening to iTunes. On a Dual 800 G4. And the noise isn't affected by anything I can think of doing. (Although you're right about USB needing lots of CPU intervention.)
