IN the config app there's settings for buffer size and such. There is an option to automatically determine the best settings. Run that and it should give you the recommended sizes. I also notice you have your format range settings set to 48000, I would change that to 44100 on both of those items. If you're sending audio outside of breakaway, say, to a sound card or another device, you'll need to have 2 cables enabled. Also, run through all the windows sound settings and make sure sample and bit rates all match up.
