Hello Friend. yes when you turn up the vol. It runs out of audio, you might have some bad bass ohms. or has short on the internal vobinas, also check the jack. there where you connect the headphones, it can be dirt, inside, or some hint of the exit for the speakers this with fissure. or the pins of the ic. amplifiers are with loose or cold welds. or underrated resistances. Cheers
