Question Logitech Z506 Front Right speaker not working, what am I doing wrong here?

Jun 30, 2020
Hello, this is my first post here..

I have tried everything I could including reviewing past posts about known issues with the Z506 but I have not been able to resolve my issue.
I get sound from all the speakers except for the Front Right speaker (the one with the Power & Volume buttons)
I have setup Realtek for the 5.1 configuration. I use a Gigabyte B250M-D3H Motherboard with Windows 10.
Using the same setup on a laptop works fine, so there is nothing wrong with the speakers.

Jack connections as per colour code
