Now, reboot the machine and it will realize that it has nothing plugged in.ġ. I'll suggest the colours mine uses and yours should be the same, but that is NOT for sure! Now, arrange your stuff so that you can have access to the rear panel and plugs so you can plug things in, PLUS be able to see your screen AND use your keyboard. Get your mobo manual and review what it says about the colours of the jacks. In your case, that would be three items (or four if you also unplug the microphone plug). To start, unplug all your speaker plugs from the speaker system from the rear panel mobo audio output jacks. If you ignore the screen query it does not use the default suggestion, it simply sends NOTHING out of that jack. It kicks in any time you unplug and then plug something into those jacks, and it REQUIRES that you give it answers.

The root of this is a feature that allows you to re-assign any of four audio output jacks to other output channels. It will describe how I have to configure mine - yours will be similar. It has caused confusion for many, myself included. I suspect you have been deceived by a feature of the Realtek sound system. (Sorry for the long post, I just want to explain the situation as much as I can.) I also tried uninstalling and reinstalling the provided drivers of my Mobo (Asus Realtek HD audio), but still encounter same issue. I tried checking all the connections of my speakers and all seem to be properly connected. Also, I cannot find 5.1 surround sound or DTS on the sound configuration of windows.

Also tried the 5.1 sound test using Realtek, I noticed that all the output are only coming from Front L-R and center. Only the Front L-R, Center and subs output sound, while the Rear L-R now has no output.

However, I tried testing the full 5.1 channel output this week by using the additional black and orange cables from my speakers and connected them to the black (Rear) and orange (SubW/C) input of my motherboard. For the past year I was only using the single green cable from my speakers to rear stereo jack input (green) of my motherboard.ĭuring that time, the Front L-R, Center, and subs are working and the Rear L-R outputs a very subtle ambient sound, almost unnoticable. Hi, I was recently trying to test whether the onboard soundcard of my Asus Z370 Prime-A motherboard would work with my 5.1 channel speakers (Logitech Z506).
