I want to connect smartphone audio to this ic (M61530F).
When I connect smartphone audio,the audio is not clear and distorted audio. When I used the circuit shown in figure 2. Now the audio is not distorted but the volume is reduced by 90%.
I have no idea. suggest circuit.
Here is the ic audio input voltage and other factors

Thank youUse a preset potentiometer instead of that attenuator. The grounds should be continuous and not have a resistor in them. You do not need a coupling cap if you retain the ones shown in figure 1.
