MBox2 Pro heavily distorted.
I have been working on a session for quite a while today. I left for lunch and left PT up and running. When I came back, the audio outputs of my MBox2 Pro are now heavily distorted. Both the line outs 1 and 2 and the headphone jacks on the front. Even iTunes is distorted without PT even running. I have trashed pref's and rebooted several times, but the sound is still distorted. What else can I try?
I am running PT 8.0.3 with OS 10.5.8. Hardware Overview: Model Name: Mac Pro Model Identifier: MacPro3,1 Processor Name: Quad-Core Intel Xeon Processor Speed: 2.8 GHz Number Of Processors: 2 Total Number Of Cores: 8 L2 Cache (per processor): 12 MB Memory: 6 GB Bus Speed: 1.6 GHz Boot ROM Version: MP31.006C.B05 SMC Version (system): 1.25f4 |

Re: MBox2 Pro heavily distorted.
Did a client spill coffee over it or something!? But seriously do you have anything to hook up to the S/PDIF outputs to test those?

Re: MBox2 Pro heavily distorted.
It will take a while to set that up, but I still have heavily distorted audio analog outputs.

It's distorted on the SPDIF outs as well.

Re: MBox2 Pro heavily distorted.
Just downloaded the latest Core audio drivers and now PT won't open at all. WTF!

Re: MBox2 Pro heavily distorted.
Uninstalled PT8 and reinstalled. It worked great for about ten minutes, then the heavy distortion came back. Please help me!

Re: MBox2 Pro heavily distorted.
If I turn off my Mac Pro, the Mbox2 Pro is still powered up from the firewire bus power. In this state the audio passing from Analog in 1 and 2 and coming out analog 1 and 2 are fine. As soon as I boot up, then the distortion starts. Weird!

Re: MBox2 Pro heavily distorted.
If I record into the MBox2 Pro into Garage Band and use the regular audio output of this Mac tower, everything sounds fine. As soon as I use the MBox2 Pro audio outputs for Garage Band, the output is heavily distorted. Audio out from the MBox2 Pro is distorted no matter what program I am using. (PT, Garage Band, iTunes etc.)

Re: MBox2 Pro heavily distorted.
This may be a stupid question but did you or your cat (if you have one ) accidentally brush up against the gain knob on the Mbox? If you unplug everything and just plug in your headphones to listen to incoming audio, do you still hear distortion? Good luck.
