Steve,
thank you for pointing out the section in The Advanced Player's Guide - page 70 for those of you reading this. While I have the guide, I completely spaced looking to it for a solution. In this case, I would purchase Mental Illusions Cyberkinesis, against hearing rather than sight (audible vs. visual), with the limitation that the character may only play music [i figure a -1/2 limitation]. This character also uses a personal focus (IAF) for this action, a skull-cap hidden by his attached Afro hair-do wig, and gains another -1/2 limitation.
Given the table of INT/EGO for devices, I would approximate a 4D6 purchase of the power would pretty much guarantee success for most non-complex devices.
