sudo pacman -S bluez
sudo pacman -S bluez-utils
sudo pacman -S blueman

sudo systemctl start bluetooth.service

Try installing pulseaudio-bluetooth package:
sudo pacman -S pulseaudio-bluetooth
restart PulseAudio with this command:
pulseaudio -k

For PulseAudio: Ensure that the pulseaudio-bluetooth package is installed. This module is responsible for automatically switching audio output to a connected Bluetooth device. If it's installed but not working, check the /etc/pulse/default.pa file and ensure the following lines are not commented out:
load-module module-switch-on-connect
If it is commented out, you can uncomment the line or type this on the /etc/pulse/default.pa file and then restart the pulseaudio
Restart pulseaudio
pulseaudio -k
And you can also restart the Bluetooth service:
Stop the Bluetooth service:
sudo systemctl stop bluetooth.service
Remove the Bluetooth cache directory:
This directory stores all pairing information, including the link keys that are causing the problem.
sudo rm -r /var/lib/bluetooth
Start the Bluetooth service again:
sudo systemctl start bluetooth.service
This will create a new, empty Bluetooth cache.
