Cannot get macbook pro to stick with AptX codec on Bluetooth.

I have wireless speakers that support AptX (KEF LS50W) and it keeps defaulting to SBC codec. So I used the Bluetooth utility to force use of AptX as described here: https://discussions.apple.com/thread/7544692

However, when the session ends and I start a new one, it keeps going back to SBC, even though the force AptX checkbox is checked.

How does macos decide which codec to use and why is it ignoring the force aptX setting on new sessions?

MacBook Pro 13", macOS 10.14

Figured out what was going on - if the power cord is not plugged in, the macbook tries to conserve energy by using the SBC codec. Once a power cord is plugged in, it switches to AptX.
