[Windows 10] Issues muting one channel

I am having the same problem mentioned in this thread. However, I cannot see how to turn off surround sound. I did check my audio driver and it is set for no surround sound. Any other suggestions?

Topic split. Your post appeared to be unrelated to the topic that you posted in. (The original topic was nothing to do with surround sound).
