The audio function is stopped working mid flight. I went to the volume screen and adjusted the volume up all the way, still no sound. I then powered it off, back on, hoping to reset it with no luck. After I landed, I unplugged each wire going to the V7 and re plugged it back in. All connections look good. The speaker works fine still as its shared with the radio. Any troubleshooting advice is welcomed here. Thanks, SA

Scott,

How did you connect the speakers? Series or parallel. It is important depending on the connection you may have overdriven the amp. Please see this link for an explanation.
