The only portion of your problems I can think of a solution to is the one regarding your volume ruining your speakers.
Make sure you have percentages in your analog scaler. This will make sure that, even when the bar on the touch panel shows volume at the maximum or minimum, the ACTUAL volume on the unit being controlled is not maxed out. This will at least save your speakers. (I suggest 33% & 51%)
As for the multiple signals being shot to the controller, I have no suggestions. Limiting the scaler should help until you have the problem corrected.
