Popcorn Soundbar

[Robby Ramirez Chavez]

So i have this strange problem with my speaker that after some use they start making weird sound like exploding popcorns and i can't find the source of the problem or how to fix it, i'm not an expert in electricity or the components and i will appreciate some help.



Problem 1; Distortion when lowering volume:

Problem 2; Distortion while not having anything connected to the speaker:

No problem 3 (more like a normal operations); Zero distortion while playing music:

Robby,

Your "speaker" may have a dirty pot (entiometer) that makes scratching sounds when you turn it.

If it is a potentiometer ie:volume knob. Try rocking it back and forth quickly. Sometime you can work the crackle out temporarily.

How does your sound bar connect to the rest of your system.
Part of what I heard on your first video link makes me think you have a digital clocking issue between components at times.

For what it's worth this is pro audio / live sound message board on the other hand you did post with your full name and in what would be the correct category for your question.
