I own a pair of usb powered speakers, and I am having trouble finding how to set the usb speakers as the default output. I found the setting where you can switch the outputs but no where to asssign a default. I took screenshot here:

You can first view your current default audio device by typing:
pactl stat
And with
pactl list
you can view all your devices.
And with this command
echo "set-default-sink alsa_output.Headset" | pacmd
you can set the default device.
pulseaudio --kill and pulseaudio --start which seems to persist the change.
