One of my speakers is not working
I have two speakers and a whoofer. But one of my speaker is not working. The sound is not coming from one of the speakers
Since you don’t provide a make and model, what follows is pure speculation:
Many speakers have a master/slave set up. That means that one speaker contains the amplifier and the other is just a speaker. In your case, can you determine which one has failed? The one with the amp usually has the connector to the computer and a cable to connect to the other speaker. I would suspect either an actual speaker failure or a bad cable as the first thing to check. It is possible that the amp has failed for one channel as well, but this is rare. Theamp in these is a single IC for both channels.
Update this with the make and model so we can provide additional details or suggestions.
