I finally decided to plug my Edifier r1700bt into my tv. I plugged the dual RCA cables into the speaker and my tv, and as suggested in a whirlpool thread, to make sure to press line in on the remote.
Nothing happens though. Am I supposed to get a response from the mini LED light on the speaker when I press line in on the remote? All other buttons (power, mute, vol up down, Bluetooth) respond with a change in LED status, but not line in. Am I doing something wrong?
Edit: turns out the dual RCA ports on the back of my tv are AV IN, so only for sound going in, not out. The only way to output sound from my tv is through digital audio out, so will need a DAC.
I'm following this thread because I had the same issue and Google couldn't solve it. Mine is plugged into my TV via AUX now which works fine but I know it could be better.
