Hey everyone...

I have just recently purchsed the final items for a small recording studio and I am in need of a bit of help...

Here's what I have:

Mbox with Protools LE 6.1

on a:

B&W G3 500
1 Gig of Ram
20 Gig HD

Well, I finally got the Mbox this week and spend that last couple of
days getting things installed and everything hooked up. Pretty easy,
at least so far. Haven't done anything fancy or messed with the
software much beyond getting couple of tracks up and running.

But I have run into a problem I am hoping somenoe can help me with.

I am getting an error that "CPU usage is holding off USB audio -9136."
It gives a bunch of options, some of which I have tried and some of
which I don't yet understand. From Digidesigns website I see that
others have had this issue as well. Anyone here have it...and what do
I do to fix it?

I called up the CPU meter to monitor the usage and it is barely being
touched, so I don't understand the error. We aren't running anything
fancy so far as I know. Strait mics into the Mbox recording 2 tracks
with no effects...at least until after. The warning shows up what
seems to be totally randomly. Sometimes 2 seconds in, sometimes 2
minutes in.

My first thought was a CPU upgrade, but since I can't really afford it
right now, and since the CPU meter is showing plenty of room, that's
out. My other thought was to use OS 9 and Protools 5.x that also came
with the Mbox. But I have a feeling this might lead to other issues I
don't want any part of. Any thoughts on doing something like that?

Anyway, for what we could get done last night, it was pretty fun. I
appreciate any help anyone can shoot my way on this.

Thanks again,
Eddie

RTFM! LOL (it's in it)

Check the hardware buffer in PT and make it bigger until the error disapear.

Thanks for such a nice reply...Don't assume I didn't try this already genious. If you're having a bad day, don't bother replying.

Later,
Eddie

As you didn't precised the thing, I could only give you the normal explanation to this peculiar error.

As you checked that then, so it's something more fishy.

Nothing new in the USB chain? No software gizmo around? No hub?

Maybe it's just the DAE etc not the last version, check it out, there has been troubles with until the end of september version and if you have the old one…

So 6.1.1 anyone? and read the update info, there are important things in it. Like you should be in 10.2.6 at least (no panther!) drive in HFS+, software update off AND repair authorizations with disk utility.

I hope it's as simple as that.

Cool...thanks for getting back to me. Rereading what I wrote it seems as I came off a bit harsh and wuld like to apologize for that.

Thanks again for shooting other ideas my way. I'll look into those as well.

Thanks,
Eddie

Just in case, an other mbox user under X has no problem with it in the FR forums…

So something IS fishy

One thing to try also is to reset the motherboard (it resets all ports)
Find a tiny push button on the motherboard near the lithium battery. Press it on start up -be carefull and don't touch anything else!

Maybe it's as stupid as that, at least I hope so
