Hi everyone... This is my first post here, and I'm desperate.
After some experimentation and luck, I get a consistent startup, and no glitches from the eGPU setup.
The issue is; that there is a buzz that comes from my monitor speakers whenever something changes on screen. The more dramatic the change, the more consistent/loud the buzz becomes.
It sounds a bit like a cell phone, using data, is placed next to the speakers.
the Audio interface I'm using seems like the culprit at the moment, but I cannot be sure.
The setup is as follows:
- GTX980 in a AKiTiO going thunderbolt direct into my Macbook Pro Retina.
- Apogee Ensemble audio interface firewire 400 into the firewire 800 port of a thunderbolt 1st gen Belkin thunderbolt hub (I tried the same configuration with the latest OWC; same results).
- Belkin hub into the second thunderbolt port on my computer.
After some trouble shooting, I've got a few things that have helped, and a few that did nothing.
Attempts that did nothing:
- Rearranging the thunderbolt signal flow, i.e: Hub into AKiTiO into Comp, AKiTiO into Hun into Comp, and so on.
- Changing output signals from the audio interface.
- Swapping thunderbolt inputs on the computer, the hub and the AKiTiO
- Testing different power sources, i.e: Grouping all to one outlet, using separate wall outlets for the AKiTiO and interface/Hub, and various implementations of power conditioners.
Attempts that seemed to help (slightly):
- Placing the AKiTiO further away from the interface.
- Changing the power outlet for the monitor speakers.
I know that this is a strange problem, and it could very well wind up being a quirk in my setup alone, but I just wanted to know if anyone has experienced this or has any advice at all; I would really appreciate it.
Thank you,

I'm going to try that now. Thank you for posting this information.

Ugh,
I found this thread too late, my Bizon Box 2 is already on its way.
The only question I have is whether or not I'm going to get the performance promised out of the GTX980 with my macbook pro.

A bit, yes... Since the card is larger than the intended length; it sticks out quite a bit from the back.
Do you suspect that the card may be effecting the speakers directly?
