I updated my MacMini (end 2012 with internal 750Gb SSD) to OS X 10.9.1.
I am using a Line6 UX2 with drivers 7.3.6 (Monkey : 1.65)
I ma using Logic X (last version)
And I have big crackling and popping issues when I try to record my guitar or bass (on both instrument inputs).
I tried to make a bigger buffer in the system prefs and/or Logic X, but it changes nothing. Impossible to have a "clean" recording without a periodic crackling noise (periodicity depending on the buffer size, from aprox 0.3 to 1 second space)
The only way to get it clean again is :
1/ to deactivate "core audio" in Logic X. But then I loose all the cool guitar and bass effects... and that's (partly) why I bought Logic in the first place !!
2/ I plug my little Apogee Jam (which I bought for my iPad) and there i gat Logic Audio working perfectly !! But I bought mu Line6 UX2 to use it !!!
So please people : fix the UX2 drivers for Maverick !! Or tell me what's wrong with my UX2 ?
I provide a sample of the sound.
