if it exits, it might be crashing.
I don't see in the output above some other device except your pc
25 module-bluez5-device path=/org/bluez/hci0/dev_40_98_4E_90_56_E3
module-alsa-card.c s16le 2ch 44100Hz SUSPENDED

Where I usually have to manually do

If it crashes I noted that restarting PA does not repair everything, but I
have to logout and login (it starts in user session). Either find out what
needs to be done after restarting PA, to fully recover or logout and login.
In any case crashing PA is not normal. I found out for debugging you could
kill PA and start it from the command line, but better disable autostart
and logout/login and start manually from command line.

I think it never paired properly - did you try blueman?
You may need to clean up ~/.pulse directory and start over. There PA writes
information about devices already used and configured.

well - in Windows they don't use bluez5 yet I guess - not sure about windows
10. In linux it is work in progress and I also suffer a lot as it is not
mature enough to be used easily, but was already adopted by the most
distros and causes a lot of headache.
