For Manjaro Cinnamon on old laptop with old bluetooth package bluez-utils was not installed automatically and rebootwas needed to produce sound via bluetooth after reconnecting and pairing bluetooth devices.

There seems to be a possibility to direct the output stream to either the built-in speakers or the 3.5 mm headphone jack. This makes it possible to connect wired external speakers to an Archlinux/Manjaro laptop/desktop and play the sound directly to the external speakers via 3.5mm jack for better sound. Tablets and mobile phones which do not offer an inbuilt 3.5mm jack can be connected to non-bluetooth speakers this way.

# If bluez-utils is not a required dependency to 
# package pulseaudio-bluetooth:

sudo pacman -Sy pulseaudio-bluetooth bluez-utils

# Reconnecting and restarting bluetooth and pulseaudio
# may not produce a sound until reboot

sudo systemctl --user restart pulseaudio bluetooth
sudo reboot
