Bug Report Intermittent audio muting

Hello, I have tried searching for a solution both on google and with the search feature here but could not find anything similar to this issue.

Up until recently I have had no issues with OBS then one day I started streaming and I noticed the audio keeps muting for me. That is to say while I'm playing starcraft the audio that I hear mutes for several seconds before resuming. This only happens while OBS is previewing my stream OR while live streaming. If the program is open but no streaming is taking place the audio is fine. My log file is in the spoiler tag, hopefully we can get this sorted out I love the program until this happened ><

Thanks a lot,
Zarkix

I just downloaded the latest test build the problem still remains but the length of the audio muting has decreased.

What's "Music Streamer II"? This seems like an unusual device for desktop audio.
