So I've recently started streaming when I got a new internet and my frames aren't being dropped but in TF2 every once in awhile I will get a horrible sound stutter, but not frames. It's rather annoying, anyone know what would cause this?

Encoding Settings:
Quality Balance = 7
Max Bitrate = 3000
Custom Buffer Size = 2250
Audio Codec = AAC
Bitrate = 96
Format = 44.1 (Tried it on 48 as well)

This doesn't happen when playing TF2 w/o a stream though. Also, you can't hear it on the stream, somehow on the stream it comes out smooth lol

Thanks!
