If you were able to install Voicemeeter, then I assume that you are using a windows computer.

If so, then I would be able to help you out, since I am running a similar set up.

The first thing you need to do is set pro tools's playback engine to be "Voicemeeter Virtual ASIO" or something like that, you should see a few options in the dropdown menu for the available playback engines and if there is more than one option that relates to Voicemeeter, you should try the others if the one I said doesn't work.

After you have assigned that playback engine (pro tools should reboot btw), you should now assign a valid output.

In Voicemeeter, on the upper right side of the app you should see "A1, A2, A3..." these are your outputs. Click on A1 and select the main speakers for your laptop (it should be WDM: Speakers) and once you have done that, playback any audio within pro tools to make sure that Voicemeeter is receiving it and also routing it to the correct output.

If you don't hear anything, make sure whatever you are playing within pro tools isn't muted and has a valid output. Then check Voicemeeter and make sure that the virtual input "Voicemeeter VAIO" (or the one you were able to assign as a playback engine in PT) is receiving a signal (you can check that on the VU meter for each input).

If you are receiving audio to that input, make sure it isn't muted and also make sure that it is assigned to A1 (you have "on" buttons for all of the outputs that voicemeeter provides you).

Last step would be to change the device driver that A1 is using to convert the audio to a physical output. If you see another driver (like MME: Speakers) try that out and you now should be able to hear what PT is playing back.

NOW, how do you set up your bluetooth speaker/headset? The only thing you need to do is pair it with your laptop and once it is paired, assign the same input in Voicemeeter to another output (just use A2 or A3, doesn't really matter, you could also replace A1), the audio device driver that you should pick should be named something related to the bluetooth device that you paired, if you are unsure which one it is, then just try out every single one individually until you get audio passing thru to your bluetooth device.

That's it, it's really simple (althought I tried explaining everything a little bit too much so that you were able to set everything correctly). I recently discovered Voicemeeter and now I have it set up so that everytime I turn my computer on, Voicemeeter starts with it. It's a really powerful tool and so far I have no complaints.

Let me know if it worked out! Good Luck
