rear speakers not working

[ghostrecon21]

My rear speakers when connected to central woofer don't produce any sounds. Is there any way I can fix this issue? Appreciate your help.

You mean the speakers connected to sub not working or is it the connection to the PC not working?

Incase its PC, are you using motherboard or sound card audio? And what Windows? More info is needed.

If using motherboard audio, try a different colour. Windows 7 used to use black for rears, Win10 changed to grey or blue to side pairs.
