Volker, it is likely that the sound frequency is not on 5.5 MHz in respect to the video carrier. So, if your sound reproduction is poor, retune the sound oscillator to 5.5 MHz. I read on Wikipedia some strange numbers because of stereo sound or dual laguage. Your old TV doesn't recognize that any way, so stick to 5.5 MHz.
