If you are running into issues with USB audio playback on your PC, it’s possible that you will see improved performance by taking the following steps to optimize your system:

• Increase the number of samples per buffer (Buffer Size). Using too small of a Buffer Size can introduce clicks, dropouts and glitches during playback. Lower Buffer Sizes can reduce latency, however, too low of a Buffer Size can introduce performance issues. Depending on which product you’re using, you can raise or lower the number of samples per buffer in the M Series Control Panel app, MOTU Pro Audio Control’s Device Page or the MOTU Audio Console. Setting the Buffer Size to 256 or 512 is a good place to start with most systems.
• If you are using a USB hub, please make sure it is externally powered. If you are using a powered hub and you’re still seeing issues, try disconnecting other USB devices or connect the M Series interface directly to a USB port on the computer. Be sure to try all USB ports on the computer.
• Use the included USB cable or a high quality third-party cable. It’s possible that inexpensive alternatives and cables that are too long can introduce problems. We recommend a USB cable no more than six feet in length.
