A similar fault is happening with me. I'm listening on an iMac. When I open Pandora sound is on only for a few minutes then the sound mutes, but in all appearances the music is still playing, the sound icon isn't muted, and the song time indicator is moving. The only way I found to get the sound back on is to close and restart Pandora, or change the station. Please advise on how I might resolve this. Thank you   ... View more
