I think I know the answer after speaking with ChatGPT but I figured I'd ask here in case someone found some hack. What I'm trying to do is play music through two bluetooth speakers using any streaming platform? I have tried connecting to two speakers through the OS and then tried setting up an AVAudioSession and messing with the options and Categories to achieve this but have been unsuccessful, and have even tried seeing if it could at least be done with playing music from the app I've created myself with a .mp3 file which also has been unsuccessful. I've read there possibly could be something with hardware/firmware that could be done to achieve this for iOS but I'm trying to see what could be done app side first. Samsung phones have the ability to dual-stream, so is there really no way to achieve the same on iOS?

These are the Developer Forums, where developers of apps for Apple's platforms ask each other for hints and tips on coding.
Your question is more of a product support one, so I'd suggest you ask it over at the Apple Support Forums. Thanks.
