Audio Issues with mixing 2 NDI Sources

[Rendal49]

I am running OBS with a MAC. I am running 2 NDI Sources (Mevo Camera and Powerpoint via NDI Scan Converter). When I mix the 2 sources the sound degrades to crackles and stutters. The OBS Log analyzer brought up Max Audio buffering. Is that causing the stuttering? My log file link is bellow.
