Can someone help me here please. All speakers working when i test the under 7.1 configuration in windows. Also in the software sonic studio pro all the 7 speakers incluing subwoofer work when i click on the speakers. But when i play a music or any sound from any other source like you tube, movies etc only front speakers(L/R) and sub woofer works .The center , side and rear speakers dont work at all. There is no sound l .I also tested some 7.1 channel and dolby /Digital audio files(assuming that may be the audio files i was playing were only 2 channel /stereo) but still no use only front left and right work . I have connected this to a creative inspire 7.1 surround system. The front L/R are connected via RCA to 3.5 mm going to green jack saying front in the sub. Rest of the sound card jacks( REAR/CENTER/SIDE) are connected via 3.5 mm cables to the respective jacks(REAR/CENTER/SIDE) on the sub.
