Stream has random blurps and bleeps

[packzap]

I'm using the Shoutcast 1.92 server and version 1.80 dsp. I get occasional yet random interrupting blurps and bleeps in the stream. The player is not cutting out or buffering. The audio sounds clean and solid straight from the board (source).

The DSP is on one pc networked to the local server (same internal network).
