I have NS-PCS41 Insignia 2.1 computer speakers. The left speaker no longer works, but does occasionally crackle or play softly. This problem is independent of the audio source (ipod, computer, whatever), so it is most certainly the speakers themselves.

yes thats the fact when you plug a headphone into any speakers the head phone will be the only one to function the speaker stops thta the circuit technically which will break the connection of power to speaker if you plug head phone

SOURCE: rear speaker not working

If you did the 5.1 sound test and the rear speaker works, sometimes you have to see in your software speakers settings,probably you need to change to 5.1 speakers
