Our setup is a laptop (internal camera) and line-in audio from the pulpit microphone (RCA jacks). When someone is at the pulpit, the audio is perfect. However, when the organ is playing prelude and/or we're singing a song, the audio (as it is received by a viewer at home) fluctuates up and down. To isolate the problem (see it was the sound system or something else), I recorded my wife playing the organ. I first recreated the problem with youtube live and webcam option. Then, I used "audicity" and I recorded her playing. The play back was perfect, no fluctuation. Conclusion, youtube live is not handling the audio very well. I've sent a comment to youtube about the issue and have not yet gotten any feed back. ..........
It may seem like youtube is the culprit because you get a clean signal in audacity, but it's also possible audacity is controlling/changing some audio setting of your laptop.
It's worth verifying the ControlPanel/Sound settings (PC), or SystemPreferences (Apple), to make sure the audio signal level is approaching 75-100% when someone is speaking at the pulpit. If you have low signal level, and the input have AGC=On, you might get some strange results.
Also, it is possible your laptop is still using it's built-in mic (while you webcast to youtube) even though you connect to the external mic jack? You could check this by doing a short youtube webcast, tap the pulpit mic and then tap the laptop mic.
It would also be helpful if you could tell us the make and model of laptop, and if you have a single TRRS audio connector or if you have 2 audio connectors (mic & headphone), as well as the cable type and any attentuator in use.
