I've been using Afterburner to record game footage for a few months now. I usually record in long stretches of about 3-4 hours. On my last bit of footage, the secondary audio track (a USB microphone) cuts off close to the 1:20:00 mark of a 1:30:00-long recording, and on the attempt before that, the audio cut out about 30 minutes into a 2:30:00-long recording. As far as I can remember, I haven't changed any settings since initially configuring Afterburner, nor have I made any hardware upgrades. I did update the AMD Catalyst suite, but I can't remember if that was before the problem occurred or not. The primary track (game audio) is fine, as is the secondary track up until it cuts out.
