Urgent Multi-Platform Streaming Setup

I need to go live on YouTube, Facebook, TikTok and Instagram as soon as possible, all from the same computer. The missing piece right now is reliable audio routing—my viewers must hear whatever is playing on the machine (music, videos, mic mix, etc.) without echoes, delays or drop-outs.

I’m not locked into any program yet, so guide me toward the best solution—whether that ends up being OBS Studio, Streamlabs, XSplit, or a clever combination with a cloud restreaming service. Once we decide, I’ll need you to install or fine-tune the software, configure scenes, set the correct RTMP keys for each platform, and prove that the audio feed is crystal-clear on all four channels.

Deliverables I’ll sign off on:
• A working project file / profile for the chosen software
• Verified live test on YouTube, Facebook, TikTok and Instagram showing synced system sound and mic
• A short checklist so I can reproduce the setup tomorrow without you

If you can jump on a screenshare today and get this humming, let’s talk right away.
