I just bought a SoundLink Revolve Plus speaker last week. With my new iPhone SE, the volume controls are behaving normally. However, when I connect the speaker to a laptop, they behave normally when I stream something off a Website, such as YouTube, but, when I play a music file using software like Winamp or VLC Media Player, the volume controls on the speaker do nothing when I press them. The volume remains at the same level all the time. Is this normal? I don't think there is anything wrong with the speaker, it's probably the way it interacts with the computer. Any ideas would be greatly appreciated. I do not want to change the volume on the computer.
