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 2×2.4 GHz Quad core Intel Xeon 8 GB 1066 Mhz DDR3 with OSX 7.5.
Hopefully it is a problem with your patch and not a driver issue. If it is a driver issue, it is much harder to find somebody who has your specific hardware. Post the patch so we can take a look and see if anything cuts out on our machines.
