A small number of Mac OS X 10.8 Mountain Lion customers have reported problems with noise or distortion occurring intermittently when recording or playing back audio over USB with Line 6 devices. Mac Driver 7.2.3 implements several changes which should improve these issues on POD HD, POD HD500, POD HD Pro, POD X3, POD X3 Live, POD X3 Pro, GuitarPort, TonePort UX1, TonePort UX2, TonePort GX, TonePort DI, TonePort KB37, POD Studio UX1, POD Studio UX2, POD Studio GX and POD Studio KB37. These improvements will be applied to PODxt, PODxt Live, PODxt Pro, TonePort UX8, POD HD300 and POD HD400 soon. Further improvements are also in progress for all Line 6 USB audio devices. We will update this document as progress is made.
If you continue to have problems with audio using our latest 7.2.3 driver for Mac OS X, please submit a support ticket.
