My speakers( sound) on my computer is not working?

If your speakers are not helping u or anyone else take them to the store u bought them at and ask for a refund if they decline it just buy a new set at a different store that is what u do if your speakers are broke.

First check you connected it right to your computer,second check the power of it, third the status of sound in your computer if its set up the right way then if still not try it with someone else computer and if that did not still work then probably the problems is with your speaker you might just have to replace it I would recommend you a site in case you need one
