Once my patcher is launch, it takes twenty or thirty seconds to have the audio cut in Max. Then no more sound until I restart Max or reselect the USB sound device (the sound card) in mac's "audio&midi setup".
I tryed to throw max preferences but without success.
I'm using Max max 6.1.6 on a MacPro 2x2.4 GHz Quad core Intel Xeon 8 GB 1066 Mhz DDR3 with OSX 7.5.
Same issue using Max 6.0.5
Any help would be appreciated.
