Mbox 2 mini play distorted sound

[[email protected]]

I use Pro Tools 11 and Mbox 2 mini
It's running on New Mac Book Pro i7 and OS 10.9.5

Problem
Audio playback normal change to distorted sound
Back to normal once you disable and enable playback engine 'Mbox 2 mini" again, but It will distorted again after couples minutes
Beside Pro Tools operation, I used Mbox2 mini as output interface for playback song from ITUNE also had same problem
I wonder it's not enough buffer for USB-audio playback?

Trouble Shooting
I tried following already
- updated Pro Tools 11 version
- set H/W buffer to max 1024
- install latest Mbox 2 mini driver
- turn off bluetooth and WiFi connection
- Directly plug into Mac Book Pro USB port

Anyone can help..? Please!!!!

USB 3.0 is your issue. You will need a powered USB 2.0 hub plugged into your MacBook Pro to stop distortion playback. Known issue here on the DUC as I have also had this issue with a late 2012 MacBook Pro and 2012 MAc Mini (Both USB 3.0 ports) with my Mbox 2.

For some reason the USB 3.0 ports are not and will not be compatible (AVID won't release new drivers for "semi-legacy" hardware)

U mean buy USB2.0 hub can fix problem?
MBox2 mini insert to hub only?
If i want to buy new USB interface, any suggestions?
How about Focusrite Scarlett USB interface?

In most cases, yes. A POWERED USB 2.0 hub can fix the issue.

I hear good things about the Focusrite stuff. Almost any USB interface will work with Pro Tools. ALMOST ANY<-----------


With any purchase you make, its always a good idea to do some research before you buy. Ask around the forums here for a recommended interface if you're unsure.

In any case, if you want to stick with AVID interfaces (For whatever reason). The Mbox 3 seems to be far more stable with USB 3.0. I got one used on Ebay for $130 US. The short time I have been testing it, it's doing well
