Multi-stream audio sharing
The frustration with public betas is that they often hide the features that surfaced during the developer preview builds. Before Android gets packaged for the faithful masses to try on their Pixel devices, two developer previews precede the beta version that’s out now.
The first public Android 15 developer preview showed evidence of an “audio sharing” feature buried in the Connected Devices menu. The general assumption is that this will likely be the user-facing way to broadcast your audio to nearby friends with compatible devices. This might also be how Android 15 does Auracast.
