Hi there, I am using a USBPre 2 soundcard from Sound Devices. The problem I am having is that on a few occasions the card has suddenly stopped completely outputting sound, usually after some 40-80 minutes of use. When it happens max continues to send audio to the driver, according to the patch' meters. Stopping / starting dsp makes no difference, but interestingly I cannot switch to the built-in soundcard when this happens. I need to re-load max to get audio back. Otherwise, it is a great-sounding device, and I am keen to know if anyone else may be using it and/or otherwise might have an idea of what is happening.
Soundcard is set to 44.1kHz / 16bit. I take care to close all applications before I plug the card in. It uses the core audio driver, USB connector is 3.0
