I recently did a search to find the source and remedy for a computer problem I am experiencing.... a regular "knock-knock" sound from the speakers on my Windows computer. I have tried googling and searching here but have not found anything that gives me any idea if this is a virus type of problem (I have run antivirus scans with most recent updates), or as some suggest it could be a sign of impending hardware failure... does anyone else have any similar experiences? Thanks.

Poping/tapping noises comeing from speakers are caused by different things or a combination to them. It is normally refered to as hardware malfunction/failure. Could be corroded speaker wires, failing filters, bad solder connection are even having nonshielded wiring and that wiring running beside a voltage line as like a power plug wire, or any other source of magnetic/electric impulse. It can also be caused by speaker cone deteriation or foriegn things(dust/bugs) Take your pick. IN THE MATTERS OF STYLE, swim with the current; in matters of principle, STAND LIKE A ROCK

I get knocking sounds from my speakers if my cell phone rings or i make a call near them. I've had other devices cause knocking in the speakers as well. Any electrical or radio devices nearby?
