I have a Revo sound card that had been working fine for months. Then one day last week the sound sporadically would stop. Finally, four days ago the sound from the card stopped completely. The interesting thing is that in analog mode the sound levels have stopped responding to inputs...i.e. the sliders are not responding to the material being played. I switched over to onboard sound and have no problem outputting the signal to my reciever. I have pulled the card out and reinstalled it, and reloaded the drivers...no dice. Has anyone seen anything similar? Also I don't have another computer to try it in, only a laptop so I can't do the obvious thing.
