Hi all, I'm using an m-audio quattro usb soundcard with my laptop using alsa 0.9.2. I'm experiencing the audio device periodically shutting down - I have to unplug and plug in the usb cable a few times before it comes back up. It is better than it was - I was getting system freezes with a previous version of alsa, so it sounds like the driver might be the culprit. I just wondered if anyone else has experienced this problem, and might have found a solution. It only occurs every hour or so of use, it's quite intermittent. cheers, dave
