I'm not familiar with this TV, but I did look through the specs on the website. I do not see any "analog audio output" listed. There is digital out, and headphones, and a whole bunch of "inputs".
One could get a mini-jack-to-RCA cable and connect from the headphone jack to the BL8000 line in. This would allow volume control via the TV. The downside is that headphone jacks often have only fair to bad circuitry so the sound quality *might* be less then optimal.
