Video demodulation and modulation is performed in the project. At the same time by taking the same signal DC blocking with the capacitor, the audio signal is passed through the MC34118 integrated audio transmission is aimed. There is no problem in the transmission of the video part but the transmission in the audio part is not provided. Is there a problem with DC blocking? I made the Idle selection of the integrated mode. The gain on both cards is equal to each other, and whichever sound signal comes from, the gain of the sound increases and switches the other sound normally. But there's no sound. What is the problem?
