2 bluetooth speakers at once problem

[xzolteu]

Hello, i have problem with my Redmi Note 5 global. I can not connect to two bluetooth speakera at once, and even when i finnaly connect, then only one plays sound. The problem was on MIUI9, have not tested on MIUI10 beta. Is there option to enable dual audio or something? Note 5 is bluetooth 5.0 device so i was suprised

Developer Options setting, but your bluetooth speakers would also need to support multiple streams.

I can connect two speakers, but only one will actually play sound at a time.
