My Soundfreaq SFQ-04 volume (#121210056) only goes down, not up. Functionally, there is no sound coming out of it. We have barely used it, primarily because it was so quiet. Today, I decided to try it again, and eventually I could get the volume down but not up. Now it is basically silent. I am using it with a Lenovo ThinkPad Yoga laptop. How do I get sound to come out?
