So my old TV finally died, so I went out about bought a Sharp Aquos LC-60LE600U. I've done from the digital audio output into my reciver, but it doesn't seem to be getting any signal. Is there a setting I'm missing to tell it to use the digital audio rather than the TV's speakers?
The setup of this TV is rather confusing. To enable the digital audio output, you need to select "Terminal Setting"- there will be a choice for PCM or bitstream, you will want to set it to Bitstream. Then there is a setting for "Fixed" or "Variable", you will want to set it to whichever one isn't the default in order to turn off the TV's crappy built-in speakers.
Most HD TV stations broadcast in Dolby Digital 5.1, you can get that with the digital output. You can't use the TV's volume control with it since the digital bitstream is output at a fixed rate. I wouldn't use mine anyways since the volume indicator on the screen annoys me. You can output a variable rate in 2-channel with the analog outputs.
