Hi, I bought the HA100 to give wireless capability for my Bose Companion 50's (which at the time only had wired capabilities). The HA100 is connected to the control pad of the Bose (where the aux input is) via an aux cable. However, after all connections, only the Right speaker works. The left speaker just buzzes lightly. 
 

Anything can be done so both speakers work? 
 

Thank you.
