Audio interface issues with Focusrite Scarlett 18i20 and USB3
I've just bought a new 2013 MacBook Air (1.7GHz i7, 8GB RAM) to use in my home studio.
I've been using a Focusrite Scarlett 18i20 USB2 interfacefor the past few months with a late 2009 27" iMac and a mid 2009 MacBook with no problems.
Any audio recorded with the new MacBook Air contains artifacts (popping, clicking, crackling) which is visible in the waveforms (I'm using both Logic Express 9 and Logic Pro X, and the problem also occurs in Audacity). All firmware and software is up to date. Artifacts become more frequent with smaller sample buffers.
I'm assuming this is due to the USB3 ports on the MacBook Air. I've tried using a USB2 hub put the issues persist. Any ideas on how to sort this will be greatly appreciated. I'm baffled as to how this is still an issue, as research has shown that this has been a well documented issue with many USB2 interfaces in the past, and yet I'm unable to find a solution!
MacBook Air, OS X Mountain Lion (10.8.4)
