In a dilemma, maybe someone can help…

My HD cable box will only output one audio line, so when my digital coax is plugged in, I cannot get access to the analog output. Now the problem: during many TV programs I want to use the Dolby fields and the resulting 7.1 surround. However, during football gatherings, and the like, I prefer a 7 channel stereo to distribute the sound uniformly around the room. The 990 cannot take a Dolby Digital input (which are most TV programs) and convert this to 7 channel stereo.

So, I can’t get an analog signal in, and I can’t covert the digital Dolby mode to 7 channel stereo.

Are their any other options to skin this challenge and get a 7 channel stereo output?
