 couldn't measure more than 4 meters with the volume at 80% (the default
 value). When I set to 100%  I could measure 12 meters.

 Maybe we can get away with an alert to set the volume to high?

 You say we must ask the user to set the volume?

 by network and the start of the sounds. I have more stable measurements
 with these values.

 Best is if bemasc could comment here, as he knows the logic in this place
 of the code, if it makes any difference.

 Yes, the change is based a tests in my network environment only.
