How do I connect multiple bluetooth devices on linux mint cinnamon?

[DavidicusBellefonte]

Hi, I am new to these forums, and to linux entirely. I simply looked for linux once, and found it was super easy to install via a usb flash and I did that and just kind of now am getting into dipping my toes in asking for help on these foruns, I have literally no idea what I am doing, and so please be patient and kind to me, this is a scary post to be making and I'm sorry if I'm already breaking a rule.

I am just trying to connect multiple bluetooth devices, which I am supposed to be able to do using Bluenan. I can connect my headphones, but not my bose speaker. I want to connect as many as I can to make a home theater easier and cheaper. I can see my devices, and I can listen to the audio on my headphones and then connect to the bose, but theres no sound. I have to click to connect on them individually, and cannot seem to find out why it won't let me do it. Please please please, can anyone help me?

Assuming both the headset and the speakers are connected properly it may be as simple as selecting the right output in the volume mixer application.

Edit: I just realized you may want to send the same audio source to all connected Bluetooth devices. Let us know if this is what want.

That is correct, I want to connect multiple speakers to one bluetooth audio output from my host device to simulate home theater setups.

This is a bit out of scope for blueman so I'll convert this to a discussion in which I can give you some suggestions.
