The good news is, this setup is done automatically for you when you add the OBS plugin. In the case that a user accidentally changes the configuration or needs to modify it themselves, here is how you should set up your OBS configuration to work properly.
The sound is very loud
Creators use various sound cards some of them might face volume challenges during the livestream. It's easy to fix.
Open your broadcast software e.g. OBS for example and select Uplify widget settings:
Enable Control audio via OBS
You will find volume settings in the Audio Mixer. Tune it and test volume using Send Preview button. We recommend -2.0 dB level as a basis.
