There is a horrible echo whenever i try to record and then there's a loud noice that sounds like a very high-pitched whistle and i don't know what to do.


This type of audio feedback loop can happen on any mic if you are playing back audio at a loud volume on speakers that are close to the mic while the mic is on - which tends to happen on Skype calls. Try lowering your speaker volume or using headphones to hear the audio, then speak into mic, and the feedback should be reduced.

I purchased a JBL PB12 (120v) subwoofer from a friend. It worked excellent for a month or so, but completely went on the fritz yesterday. Whenever I turn it on, I get a loud whining noise, that starts high...


It sounds like something on your main board of your amp is going out. It is most likely the finals, or as you said a capacitor. Test the port with another speaker, if al is well then the wooferis bad. if not you will have to go inside the amp for repair. Depending on the brand it can be a little complicated. Try and narror it down to the proper componet, post back the results and we will go from there. Also is this sound comming from all channels or just the woofer?

Van brakes squeal/whistle even when stopped


Sounds to me like a dry, loose or worn serpentine belt. With the motor idling, lightly spray the serpentine belt as it's spinning with WD-40 or other oil based lubricant (Don't spray near the alternator). If this doesn't work, turn the mortor off and check the tension and for cracks or worn spots. The brakes will not squeal when you are completely still.

My Kirby G3 makes a loud, high pitch whistle with the hose


I would say you either have something stuck on the impeller or there is a piece of paper or something stuck inside the hose. its not clogging the hose but when the air passes by it. It is making that noise. If you find nothing you may need a repair. May have a bad bearing in the motor. Actually you can also try inspecting the brush on the head. It removes easily from vacuum and should spin freely and quietly.

Occasional 'whistling/whining' from back of TV


I wonder if there is enough air circulating around your equipment?? My DVD recorder makes a sound unless I open the doors on the cabinet that contains all of my equipment. The cable company says it is a fan to cool down the units.
