I'm not following you. You mean you tried it and you didn't get the squeal, or you did get the squeal, or you didn't try it, or...?
I didn't try it because to figure out what's going on, I want to be using the least amount of pieces. To find out if it happened without the speaker on, I'd have to insert a recording device into the equation. Nothing else to prove it otherwise.
