My subwoofer and speaker are only playing sound from the left channel.

[jagomaster74]

I have an old speakers + subwoofer setup where the speakers cannot play sound unless its connected to the subwoofer and uses speaker wire to connect to the subwoofer. Recently, When I connect the speaker wire to the subwoofers, the speakers only plays sound from the left channel. There's no problem with the other speaker, because when its connected to the subwoofer I can still play sound through it via an aux cable. And I know its not that I have my sound set to mono, because when I tried to use an interface, the right channel wasn't playing at all. Help pls

how you connecting to the output of what i assume is a pc? Jack plug etc? Could you try head phones in same output see if that gets stereo if not then the outputs the problem. My 2 cents.
