Would it really take that much effort to run some analogue audio cables from the STB to the AVR? Or listen to the HDMI signal on the TV? Each thing you eliminate or confirm helps with the diagnosis.
For example, if analogue audio works, that rules out that signal.
If HDMI works, then it's not the digital signal, but could be something in the STB with regard to DD5.1 to the AVR, or the Optical connection...
