After days of reading articles, trying many things on my material, I finally come for help.
I recently bought :
Imac OS X Yosemite 10.10.5
Steinberg UR 22 mk II
Yamaha HS 80M
I downloaded every last driver for Cubase AI 8 and USB/firmware.
My problem is :
a noise appears everytime i open Cubase. It disappears when closing Cubase.
That noise does not seem to be modified by electric connections (every monitor, and Computer is on a separated wall power), my cables are new ones, made for monitoring.
That noise is not linked to any instrument plugged in my audio interface.
It sound like a high pitched buzz, and is permanent.
A second sound can be heard, and its pitch is modified by changing buffer size.
When i play a youtube music, there also an annoying sound behind the song, it’s not the same as with cubase, but it’s still there…
May someone help me ?
