Is it both analog,and digital loss of sound. Can you get the weather in your area as IowaGuy1603 asked? I had lost digital sound after a download,but could still hear the analog frequencies. It happened when I upgraded my firmware,and DSP on my other computer. After much pulling of hair, I went to my sisters house,and downloaded Firmware,DSP,and the Library. It was my computer. I have changed computers to a more up to date one.
