i bought a new computer with MSi K9AGM4 mother board
which has a built in jack detection and supports 5.1 channel audio
i tried installing the drivers from realtek's website but i still do not have jack detection nor does the 5.1 audio work.
in fact my rear left and rear right are being played in the respective front speakers (NB i used the audio clip in the following url
