Any one having noise issue running RME Fireface UFX with Logic Pro X on OS X 10.9.1?
I can't seem to get a consistent and reliable no-noise recording. I'm running OS X 10.9.1. My Fireface UFX is updated to firmware v353 and drivers are 1.91. I'm recording into Logic Pro X. I can occasionally get a good recording but eventually all I get is noise. Once the system is in this state I can sometimes reset the core audio by disabling and enabling core audio in Logic preferences. Not sure what the issue is. I called RME state-side tech support. They suggested it was some kind of USB bus issue. So I removed everthing on the bus except for the Fireface UFX. Still no luck. I have a brand new iMac (i7 with 16GB ram non-fusion drive) and a brand new Fireface UFX. Any help would be much appreciated.
iMac, OS X Mavericks (10.9.1)
