I am running the latest version of OBS Studio (and encountered the same problem on previous versions), on Windows 7 64bit. When streaming or locally recording, audio from my USB capture card (IOData GV-USB2), will stop being recorded when specific events occur in game. Looking back through my VODS, every time it has cut out midstream coincides with a power bomb explosion or item acquisition fanfare in Super Metroid. Potentially of note is that these are particularly loud sounds. It does not always (in fact, usually) cut out on the first occurrence of these sounds streamed. I don't stream enough other console games to no if this is an issue in any other game.

Of particular note, the green volume level bar in OBS for the capture card continues to indicate that audio is being received normally. Restarting the stream/recording or restarting OBS does not seem to be enough restore audio as the issue carries over. Restarting my computer does seem to fix it though.

My first thought would be a USB buffer issue, but I do not know if the volume level bar would continue to update if that were the case. Other programs, including original OBS do not seem to encounter this problem as well, though original OBS did frequently have synchronization problems. This seems like a likely culprit as I've had USB buffer issues previously due to running a relatively resource hungry USB sound card.

Here is the log file for the example stream linked above (pastebin link as it exceeds the character limit): http://pastebin.com/qrd9uWhg

Thanks in advance for any help/suggestions.
