No stereo audio on Cable TV

[old_tv_nut]

At one time cable systems were duplicating channels in analog NTSC and digital. The old cable boxes were analog of course. Now that they have gone completely to digital signals, I see no reason that the HDMI output of any box should be mono. So, yes, it needs more investigation, but the cable company is incompetent if they can't even tell you whether it's mono or stereo coming out of their box on the HDMI cable.

On the digital adapter/AKAi combo, I assume the "coax jack" is the RF tuner input, or did I misunderstand?
