Power surge to audio port possible?

[Game_man]

Thanks in advance for reading long query.I have pretty old Creative speakers (2 sp. & 1 woofer),of 2007,which sometimes produce cracking sound when,the speaker volume button is turned on from off position.So is there any chance that reverese current is sent back by those old speakers,from speakers power adapter (which fell down few times on ground) to motherboard's green audio port and afftecing/damaging the system.

It is realy realy small chance to happen that, to be sure take a multimeter adn measure the current on the jack port when you turn on the audio system, you just may have noise on the circuit, noise can produce ugly sounds but it is harmless.

You cannot measure with that, that is made for 100V, your speakers and motherboard will be long fried before reaches 100V, it will be a mather of single digit values.

So what can be done now?It would be very foolish to buy a multimeter.

Owning a multimeter is not foolish. They are also helpful when you have other electricals with problems.
Also the chance of a power surge going to your headphones is very low, I mean EXTREMELY LOW! if you think you are prone to an attack of an overlotion (not sure if thats a word) of power, Assuming your headphones are still warranted, pack them up and ask for a refund/new pair. (if you have to lie about them being dodgy)

P.S. If they did get too much electricity they would make a screeching noise and you would most likely not get hurt. Maybe only some ringing in your ears for the next 10 minutes.

P.P.S There is a good chance that your house is rigged with tripper switches, When the tripper switches sense alot of electricity they will get triggered and all the power in your house will be shutdown.
