Question / Help Audio Hiccups/Stutters

jayee · Jun 25, 2014

I'm having issues with the audio having a hiccup affect, pretty much as stuttering. The hiccups occur once every 3 seconds or so. I've searched around the net for similar situations and applying other's solution to no avail. I've messed with buffering/bitrate, changing around the scene buffering time and also checking audio sync in the advance tab. Nothing has helped.

Regardless if I'm recording directly to my HDD or if I'm streaming on Twitch, the hiccups/stutters are still there.

Here's an example of what I'm talking about: http://www.twitch.tv/jayeeyee/b/541713893

Bump, anyone?

dodgepong · Jun 27, 2014

Seems odd, I'm not exactly sure. Does it happen if you run at 30fps instead of 48? OBS doesn't appear to be overloaded, but 720p48 is higher than I would expect that CPU to be able to perform.

jayee · Jun 27, 2014

Surprisingly, my system isn't at all bogged down when streaming at 720p48. I've tried further down scaling as well as native resolution all at 30fps and the problem continues to persist.
