soundcard issues

March 7, 2014 | 9:33 am

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

MacBook Pro, Intel Core i7, 2,3 GHz, 16 GB ram, OS 10.9.2, max 6.1.6

Yes, I have contacted Sound Devices support. They did not test specifically w. max. They got the specs of my machine and set-up etc. I can do with regarding the card is set the bit depth from Macs audio setup, as s/r is controlled from max’ audio status window. They got this info about a week ago, but so far no response, which is why I am asking here…

What puzzles me is that the soundcard sits on the core audio driver which has never given me any problems when using the built-in soundcard. So I might tend to think that it is a soundcard issue, but on the other hand, I have never had the audio cut out when using other dedicated audio software (ableton, audacity, vox).

The soundcard does not give any error message on (leds) – it just dies.
