LG 32LS560S to Denon amplifier

I bought the converter, so I (LG32LS560S) can operate on my Denon Stereo System my new TV. Connection and function are easy. From the quality I expected more. But since you have probably grab even deeper into their pockets. Although the noise when the TV is still bearable, but still clearly heard (a point deduction). The volume control on the amplifier I must turn up to almost half, so I can get acceptable sound. I'd expect anything else and there are two of me also point deduction. It's totally annoying when you have watched a movie on the eve on the hi-fi system and the next morning turns the tuner and forgets to put the amplifier back to normal volume :(
