I am running Windows 10 Pro and I have two identical standalone Bluetooth 4.1 + EDR, A2DP speakers. I noticed that I can connect multiple devices to the same speaker (e.g. my PC and my phone), but I can't connect my PC to multiple speakers. Is there any software or hardware that would allow me to play audio on both speakers via Bluetooth in stereo? Preferably, I am looking for a solution which will play left channels on one speaker and the right channels on the other.
My current solution is to use an app called SoundSeeder, which lets me play pre-recorded audio on my PC and phone in sync, thus letting me connect one speaker to the PC and the other to my phone. The problem with this is that you can't play stuff like YouTube videos or anything that is not pre-recorded and the audio gets out of sync often, so it isn't really stereo.
Any suggestions would be really appreciated.
