I have an odd problem. The FM raido stopped working. This did not correspond to a firmware upgrade or change of any kind. When the tuner is selected, I can tune into staions, but there is no audio. The really odd thing is that when I record from the tuner, and play back the the resulting file, I get audio. Jus no audio from the tuner it’s self. The MP3 stuff works fine. Has anyone else out there had this problem?
