I have an Acer Aspire T135 desktop with sound card issues. The system is about twelve years old, and I bought it new. The sound quit about a year ago and I have tried many ways to solve the problem along with remote access tech. support with no success. I have been told the card has failed, and needs to be replaced with an external sound card. I am hoping that this is an issue I can resolve " In House " with out all the replacement fuss I've been told. If anyone out there knows how to fix this problem, I would certainly appreciate the help. Thanks.
