Would I be right in thinking that the default sound alert will play for a poi if no talking sound file is loaded with the GPX & BMP? I have loaded some poi with matching wav files which work fine. Before I deleted and reinstalled via poi loader and sox file, I was also getting the default beep as well. Maybe when I manually deleted the Garmin GPI files, I only get the custom poi sounds for the ones installed. Originally had the Garmin sample files also loaded.
unusual that ur not hearing any spoken alerts. Make sure that each poi has exact matching GPX ,BMP,WAV files that you load, Also you need to use the Sox.exe file , which needs to be in the POI LOADER directory if you use .wav files. For me the .wav files worked instead of the MP3 files, even though my 1390t supports both types of sound files.
