Hi, I have had my Altec Lansings for five years. Last night, they were fine. Today, I have to crank the volume up on them to get even a modest sound. No cracking, no power surges, there is sufficient power to the device it seems (I tried different sockets), and my computer settings have not changed. Any suggestions? I think the model is REV A00, black with a silver front, sitting on a silver circular "halo" type stand.
