No sound from Left & Right channels :- (

Hey

I've decided to reinstall my windows. But rather than using existing drive. I ended up getting new one so I'm now dual botting.
Now the fun part, I decided to take my time, do restarts be slow with it and make sure its all "good" this was not part of the deal.
I've used my trusted APO sound app (Equalizer APO download | SourceForge.net). Everything was fine until today...
I noticed no sounds! Left & Rich channels have no sound(5.1 set). Centre & rear left/right appear to work. Subwuffer is somehow lost too - partially.

I've no idea how to fix it. I've uninstalled apo, drivers, reinstalled all from 0. I mean WTF ?! I never had anything like this before.
Any ideas?

There is literally no sound coming out of green jack, I tried swapping it with back. I also jumped bot to old windows, sound work fine there. Its only here broken ;[

Windows 10x64

Windows 7
Local Time: 21:00

and indeed your computer spec
OS: Windows 7

or windows 10 and if so what OS is it dual booting with

Disconnect the original drive
Boot from the newly installed windows on the new drive
The reconfigure the sound settings on that drive
See if it then works

I've found that there's differences in the sound adapter on the motherboards and also with add-in sound cards, mainly in some have only 3 ports with the center light green most commonly used with output to speakers and other setups have 6 ports, have seen the light green and black in use once but there may be other combinations with them. On the 3 port setup one is the output, one is the line in and one is the microphone.

I have no knowledge of this APO download but the sound should be very easy to set up on this board
From your user manual please see page 22 of the online pdf
https://download.gigabyte.com/FileLi...055550bfb4677b

you will see that the ports are listed i, j, l, m and n

You connect the speakers as shown on page 22
i - centre/subwoofer
j - rear speaker
l - side speaker out
m- front speaker out
n - side speaker out

BEAR IN MIND please that L is also line in and N is also MIC IN
so as it says on page 22
you need to configure those ports to be side speaker out if that is what you wish

That is done by right clicking the speaker icon in the notifications area and selecting sounds
you then on ther window that opens select your realtek HD audio and click the configure button
you then on that window select the setup you wish - with the speakers connected as in the chart on page 22
you click next and it will proceed to that diagram
you click next again until you get to CONFIGURATION complete
when you then click Finish

You may go back at anytime from those windows to return having set them, to the layout of the speaker window, where you may click on any individual speaker to test the sound.

I suggest you try that WITHOUT this third party app and then when you get that working you will then know of the problem is the audio jack sockets or your speaker setup
As at the present time you do not know if it is the setup or the third party app

Thought this may help
