Right click on the device and select "Update Driver Software.".Find your uninstalled audio device, (it should have a yellow exclamation sign on it).Go to Start->Control Panel->Hardware and Sound->Device Manager.Yes, all of them.Īt this point your USB device should not be recognized by windows. I was able to get 64 samples with my M-Track and this should work for yours too (and just about any other USB device). The speed of your computer and the speed of your USB audio device (2.0, 1.0, etc.). This will, of course be dependent upon a couple of factors. I had this same problem using the M-Audio Driver. As an anecdotal example, my previous computer couldn't get anywhere under 30ms round-trip (input + output) without stuttering horribly, but a different computer using the same interface was getting closer to 16, and I've since switched out audio interfaces and now can usually get around 11 unless I've got a lot of CPU or memory intensive software running. I don't know exactly why this is, but different combinations of audio hardware and computers seem to have different minimum useful buffer sizes.
You can experiment with different settings to see how low you can get the buffer before your computer is too interrupted by general use to keep it stable. The shorter the buffer, the shorter the latency, at the risk of an interrupted signal. This prevents audible clicks, pops, and start-stop stuttering when recording or playing back audio. The idea is that as your computer jumps between tasks, as computers do, there's a safety net in case the computer doesn't get around to processing more sound data. The buffer is a buffered set of samples between your sound hardware and your computer. Generally, ASIO4ALL (and actually, any low-latency audio driver) will expose a parameter for how large the ASIO buffer is. If you're on OSX, it's Core Audio instead of ASIO, but same idea. Play around with the ASIO buffer size, assuming you're on Windows.
