I've got an Aztech Sound Galaxy Waverider 32 Plus (AZT-2316/A/R) soundcard. I think it must have a component which is heat-stressed and out-of-spec or near to failing. The card gives a high-pitched squeal when in use for a while and the sound quality over the Internet for applications such as Firetalk and others deliver a quite obvious "munchkin-like" quality to the sounds and voices (either that or they're inhaling vast quantities of helium on a regular basis).
If I pull that card and let it cool off or place it in my refrigerator for a little while and then reinstall the card - the card works perfectly and sounds for the world just normal. After a while though it slips back into "helium" mode. Does everyone agree that I'm just looking at a soundcard replacement and that there are no extraordinary efforts I need to pursue first to get the thing to work.(I thought putting the card in the refrigerator was already above and beyond the call of duty.) The card is five years old.
Any takers on a correct answer - although the answer seems pretty clear to me?
