Problems playing audio on Bluetooth Speakers

[spock_42]

Hi all!
I've been having trouble getting audio to play from my Linux Laptop (Ubuntu 18) on my Roberts SB1 speakers via Bluetooth.
I've been able to connect to my Bluetooth headphones without issue, and I've had no problems connecting other devices to the speakers, so something is fishy between the two of them.
When I initially connect, there's a split second where the audio plays, then it just stops.
I use blueman manager, 2.0.5.
I'm only able to select the A2DP Sink: AA2 Audio profile, others refuse to connect.

Would appreciate any suggestions, and happy to provide any other details.
