Hello guys

No 5.1 channel sounds while trying to setup a on-board “RealTek” audio output? Just forget about 5.1  & setup the speaker as 7.1 channel. For some reasons, Selecting the speaker as 5.1 causes the processor to channel the rear audio to “side speakers” which are actually not “existing” in 5.1 setup.

Give it a try folks & it works!
