I recently purchased a Radeon HD 5450 for my HTPC. When I hook it up to my TV, Windows 7 reports that the audio device only supports 2 channels. Why is this?
I've read that this will happen if the device it is hooked up to doesn't support 5 channels, but there is an Xbox 360 and PS3 hooked up to the TV as well, and they work just fine in 5.1 surround. The TV is also set to use the external audio device which is a surround sound system via Optical audio.
Why would only Windows say the TV only supports 2 channels, and how can I get the system to understand that the TV does support 5 channel audio?
