I am currently looking for alternative solutions that are simpler and require less setup for Windows. This is possible with bluetooth 4, so I'm not entirely sure why we have the dual audio feature with bluetooth 5 then. On MacOS you can use the audio midi setup utility: It should theoretically work on Windows XP and up.

If you want to use Voicemeeter for more than 2 devices, you can use the more advanced Voicemeeter Banana or Potato. In my case it can sometimes use a high amount of CPU but restarting it usually solves that. Another downside is that you have to launch Voicemeeter every time you want to play audio through it. To less experienced users it can be a bit confusing and messy. Voicemeeter is donationware so it can be used for free. Like Cpt.Whale commented on Windows you can try two things: I have found a solution for MacOS and Windows. Audio streams would also introduce lag, so it would also be nice to be able to set a delay for each device so they play at exactly the same time because otherwise it would sound more like an echo.Īny suggestions would be appreciated, I will try some other stuff myself and share it when I find anything helpful. I couldn't find a light weight Apple HLS tool nor a simple library that lets you host audio streams from a C# program. The same way online radio or YouTube stream audio. I do not have devices with bluetooth 5.0, but maybe there would also be a way to do this by streaming audio from one device to for example a local web page you can access on your phone and then playing audio from your computer and phone to each speaker. Some Samsung phones have this feature but I am not sure if it's exclusive to galaxy buds or if it works for all devices, as the feature is not present on my galaxy A51. I assume it's likely not possible on iOS due to the locked down operating system. I would like to know if this can be done for Android, MacOS and Windows, preferrably with the option to choose what device plays left and what plays right. They connect as audio devices but I just can't select them all at a time.

I can connect multiple bluetooth devices to my laptop at once for example, same goes with my macbook and my phone. When using Google to search for information pretty much all websites say you can do this but only with bluetooth 5.0, which I don't think is true. I would like to be able to do this for connecting multiple bleutooth speakers, earbuds or airpods at the same time and playing audio to at least 2 devices at once. I have multiple bluetooth audio devices which I want to be able to play audio to synchronously.
