Hi. Hoping someone can help me. I have an old set of Harman Kardon computer speakers (the original Soundsticks). They are powered (plug into wall outlet) and connected to my old iMac via usb. I would love to set them on my desk at work and connect my Galaxy Note 2 to the speakers to listen to my tunes/Pandora/Spotify, etc. Can't connect them to my work computer due to company rules. I bought a usb-to-micro-usb cable but nothing happens. Do I need some type of driver? Am I just out luck? The audio output mode on my phone is set to play external speakers when docked. Any help would be appreciated. Thanks!
