Bursts of white noise

[lnl]

Sounds like it could be connected to the "ignore buffer underrun errors (-6086)" setting?!

- go to Hardware setup > find the "Ignore b. u. e..." section

- it can be selected/deselected for recording and playback separately

- when it is selected, it produces a burst of sound instead of stopping PT + showing warning dialogue

You can cross check to find out if it has anything to do with your problem. Worth a try I think.

Definitely not the issue in my case. The white noise I was experiencing was quite a bit different than that of the ignore buffer underrun error-- it would last for entire regions on random tracks-- not just sporadic.

Just to make sure that I wasn't insane, I pulled the drive out of the enclosure and hooked it up internally again-- as suspected-- no noise blasts. It's the control chip from the FW drive enclosure for sure. Just ordered a new one from OWC with the Oxford 911 chip.

I suspect that this is probably the issue for some other people having similar problems.

I'm definitely using a firewire drive with an oxford 911 chipset and 7200 rpm. And this problem has persisted with two seperate firewire drives. But I'll definitely try using the drive internally to see if the problem goes away. Anything to make it stop!

But it does seem like we're having the same problem. On random occasions the noise will burst through my system and sound for the duration of my audio regions. I've noticed that unplugging the usb cable connected to my mbox also makes the problem go away but then rather obviously my session crashes.

This did not happen in os 9 using the same drives. It seems specific to os x.

Hi Danielle,
I did notice in one of your earlier posts that you mentioned you had an oxford enclosure-- I'm curious to see if switching your drive to internal makes a difference.

The only other issues I can think of in your case would be that maybe the drive has journaling enabled (which it shouldn't be for an audio drive), or maybe an issue with the drive cache?

Since it didn't do it in OS9, I'm leaning toward the journaling. Of course, if you install it internally and it works, obviously it would have something to do with the enclosure.

Good luck.

I have recently got this burst of noise also. It blasted just for a second and quit, no crash.

I don't have any firewire drives, but I do have a QPC QueFire firewire cd burner. I don't use it in OSX because I don't have Toast 5 yet, but the burner is pluged in.

Having the same problem, random bursts of white noise on playback on ext drive only.

It seems the problem I was having was related to the firewire drive not being quick enough.

The white noise bursts definately got worse when playing back close to dense edit points across several tracks.

I transferred to the older Lacie 80G drive (the first ones that were fast enough to run a lot of audio. I've been running 64 tracks on a MIX+ off those drives for a couple of years now.)

So far no white noise bursts.
