Sounds like the kernel is just not consuming any data in the bluetooth
socket.

If paplay talks about draining, it means that it reached the end of the
file. Is the file very short? Could you try with a longer file? I don't
expect that to work any better, but at least that will rule out the
possibility that it's only the draining that is failing in paplay.

The device rate is 8000, so the active bluetooth profile is HSP/HFP. Is
that what you want to use? "Bluetooth speaker" sounds like something
that you would rather use with the A2DP profile. You can switch the
profile with "pactl set-card-profile CARDNAME a2dp_sink".
