Question / Help Popping/Crackling noise streaming Super Mario World

[Waz]

Hi, I've suddenly got an audio issue after a few months of it being fine. I'm getting a recurring crackling noise with the audio. It doesn't seem to have a pattern to it, it just happens throughout the stream, but does tend to be when something more audible happens, such as a jump or collecting a coin. Sometimes it's happening a lot, sometimes it can go a few minutes not happening. A good example is at 2:07:57 when a fireball hits the koopa at the bottom right of the screen, you hear a pop and it also gets quite crackly towards the end of the level (whoops, forgot to include this http://www.twitch.tv/wazmannen/b/616812497).

I'm speedrunning Super Mario World played on a Super Famicom and CRT TV, captured with a GV-USB 2 cap card and amarec.

Make sure GX mode is disabled on your sound card. Also see if increasing your Scene Buffering Time in Advanced settings to 700ms helps at all.
