Troubleshooting Source-Connect Link

This article is part of the Source-Connect Standard and Source-Connect Pro/Pro X 3.9 User Guide. This guide is also applicable for any issues with the Source-Connect I/O plugin in Source-Connect 4.

The main issue with Source-Connect Link may be additional latency. To mitigate latency between Source-Connect and your DAW try setting your plugin buffers and DAW host processing buffers to the lowest possible setting.  

For example in Pro Tools open Playback Engine settings and lower the Host Processing buffer to 256 or lower. Source-Connect Link is a slim-line plugin and should not incur much additional CPU usage.

Another issue may be that you are not receiving audio from Source-Connect to Link on macOS. To resolve this make sure that Source-Connect and your DAW launch with the same sample-rate; you may also delete the Audio Midi preferences and restart your computer.
