When I power on the Bluetooth mp3 FM module, the volume level increases to the maximum. After that when I apply to pot, then the volume level decreases as per my wish. My problem is that how to control the volume level as per pot setting when power on the Bluetooth mp3 FM module. I am using the LA4440 audio amplifier for it. Please help me in this regard.
You said, "when I apply to pot". Where is the pot? If the volume control pot is at the input of the LA4440 amplifier then set it to the reduced maximum level you want and use the volume control pushbuttons on the MP3 module to control the volume.
