Audio problem
Hi
Recently upgraded to iMac 27 3.4 FD and Apogee quartet. Everything fine except trying to record audio in. For example, when I plug my guitar in it will sound fine for a few seconds and then the latency (regardless of settings in Logic) will jump to about half a second. Also the sound crackles, not overload distortion, more like the sound of a faulty lead.
Anyone else experienced this or have any suggestions?
