Default Distorted playback

I'm getting horrible screeching, hissing, crackling playback when Pro Tools 11 is running. It's never any louder than the computer volume level, but it happens when I play a youtube video or a song just by having Pro Tools open and idle in the background. All software and drivers are up to date. This is the newest Macbook Pro, and my first run of trying to configure PT on it, so I'm wondering if it's the audio card or just some basic set-up issue. I've scoured forums to no end but nothing about my situation. Thanks in advance.


- Mac Yosemite: 10.10.1
- Apogee ONE (iPod and Mac) - this was not plugged in at the time--hisses regardless
- Pro Tools LE 11.3.0

Macbook specs:

2.5GHz quad-core Intel Core i7
Turbo Boost up to 3.7GHz
16GB 1600MHz memory
512GB PCIe-based flash storage 1
Intel Iris Pro Graphics
NVIDIA GeForce GT 750M with 2GB GDDR5 memory
Built-in battery (8 hours)2

I'm having this identical problem, and I am on a PC with Pro Tools 11.3, Windows 7 64 bit.

Anyone with any clues on this?

A similar problem happens for me but it goes away if I turn on/off my Mbox
