I am using a 2 channel rca input so i can play music from echo dot(a reason i bought the speakers).

Audio sounds fine from the front and centre speakers however the rear(or side) speakers are distorted and seem to play some of the instrumental parts but not play vocals, even if i play an audio-book the vocal does not come through so it is silent.
Its not the speakers because if i use 3.5 outputs from a 5.1 sound card the sound is fine on all speakers.

need 5.1 sound card. for perfect sound, in stereo mode, simulate 5.1.
