Query: Great sound, but DEFECTIVE

Like other reviewers, I just experienced the maximum volume problem with my Athena iVoice. I turned on the system and the volume went to maximum and would not go down. Totally NOT COOL as we use it in our twin babies' nursery! The volume buttons on top of the unit are unresponsive. I finally was able to lower the volume using the remote (once I found it) but the buttons still don't work.AVOID.
