I have a simple Bluetooth speaker that always seem to cut off its speaker circuit when the audio stream goes silent. This makes an audible popping noise, which is repeated when the stream starts delivering actual sound again. As long as there's sound playing continuously it works ok.
The problem is that the speakers are always activated too late, resulting in skipping the first syllable of a sentence in an audio book or in a video with silent parts.
Another problem is that it also happens whenever the volume is very low at the source, which means I don't get to listen to the actual audio, just a lot of popping noises.
The IC responsible for driving the speakers seems to be
M6008N. My question is if it's possible to make it stop cutting off the speakers just because the stream is silent?
- The problem only occurs when playing from a digital source, i.e. Bluetooth and not through line in.
- It only occurs when played through its built-in speakers, i.e. not using its line out port.
I could only find data sheets in chinese of the IC.
Am I even looking at the right thing?
The only other thing of interest is a tiny premade bluetooth module board which I can't do much with. It seems to take care of storing the sound effects and handling the mandatory worthless microphone, but I can't say if that raises the probability of the problem being located on it.
