Audio Output too low

Hey Guys.

Some of my Viewers on Twitch told me that my Streams are quite low in Volume, compared to most other streamers.

The inputs seem fine so far. (As loud as possible, without getting overdrive/crackling or any other distortions).

The Soundquality, balancing etc. is okay as well.

It's just the general output which is too low.

Is there a way to amplify just the output of Streamlabs OBS? I tried using other Software, didn't have that issue there. But I'd love to continue using streamlabs obs.

Thanks in advance!
