The audio codec used on my motherboard is ALC889A, after installing audio drivers, when trying to perform the speaker test function in Realtek audio program, why will only the front left and front right of the S/PIDIF speaker have proper audio output? Also where can I find DTS related functions in Realtek audio program?

ALC889A audio codec does not support DTS decoding function.
The DTS multi channel function is provided through the playback program, when using playback program that supports DTS decoding function such as Power DVD to play DVD movies, S/PDIF speaker will automatically output multi channel audio properly.
