I have successfully downloaded & installed Ham Radio Deluxe version 5.22.0.02 to connect my Icom 756 to my Dell XPS computer. This is my first crack at trying any of the HRD versions. Everything has connected properly...I can change frequencies, make various adjustments etc. however I am getting no sound from the computer as I thought I could also expect from this program. My sound system is working properly on my computer in all other areas and in checking my volume mixer I see that Ham Radio Deluxe is accounted for and 'on' however no sound comes through my computer speakers. Is there not supposed to be sound from the computer ? Do I just continue to listen to my Icom for sound ? Or am I missing something here ? Any suggestions would be greatly appreciated !!
