Some devices has an internal (remote) volume control that can be adjusted through the bluetooth connection
If there is no GUI and/or buttons on the device to control the volume, try these DBUS commands.
To find the node name use this command

Then use these commands to raise/lower the volume
dbus-send --print-reply --system --dest=org.bluez /org/bluez/hci0/dev_00_11_22_33_44_55 org.bluez.MediaControl1.VolumeUp dbus-send --print-reply --system --dest=org.bluez /org/bluez/hci0/dev_00_11_22_33_44_55 org.bluez.MediaControl1.VolumeDown
