...system.? I own a Sony Vaio home entertainment system, purchased about two years ago. It has not been updated since its purchase because it was not connected to the internet. After having it unpluggle for a few weeks, I plugged it back in to discover that I had no sound. All the proper wires are plugged in, including a standard HDMI wire. I know that HDMI can move sound because it is doing so for my PS3. Any suggestions to help me get sound to this system?
