G5 - Noise Options

[macmaster123]

Hello

I've got a question about using the PowerMac G5 for musicproduktion. I just got my G5 and everything seemed fine until I discovered some kind of chirping sound when I was using Cubase. Every time I moved the mouse and especially when holding down the mouse button on the graphic eq the sound became very loud. Also a tone keept repeating it selv once evry' second. These noises got higher when I turned the performance up HIGH insted of AUTOMATIC. After a serieus search on the net I discovered that this is a known problem for many users. But I've got a few questions :
1) Are there anyone who do not experience these problems?
2) Are there any other way to get rid of the noise than to use the "CHUD Tools Nap mode Fix - nap of" - and does anyone know if it is a serieus problem to do this "nap off" for a longer peroid of time. I know that the went is going to be running a bit more and it doesn't bother me, but is it a problem for the hardware inside the mac ?
3) How do you use the G5 for serieus music production, disabel the nao or live with the noise ?
4) Are there any reports of people getting less noise after replacement of the PS which seems to be the problems ? Any new supplies beeing produced ?

I'm quite frustrated and considering returning the mac, but I would really like to hear from you folks who are using the machine on a dayli basis... I'm a regular PC user who just made the switch to mac...

What is your core audio buffer size? I know you're using Cubase but some Logic users have reported a chirping noise due to CPU load when using 32 or 64 sample buffer, but with 128 or 256 sample buffer the noise seems to not be audible anymore.

The noise is there no matter what, I have tried it all. I'm using a G5 dual 2 with 1.5 gb ram...

Try this link: Apple recommend NOT to use the CHUD Tools nap option to solve the noise. Read on....

Cheers and good luck!

Apple's are great music creating devices, but lately there are some issues here and there, I guess there's a real money making frenzy in Apple's management that focusses them on consumer products like the iPod (have you heard it made them earn 6 times more than last year!!) No worries though

I get this noise - What causes the sound when the mouse pointer moves?

It's only an annoyance though. I've yet to master playing a keyboard or recording an acoustic guitar whilst moving the mouse....
