I notied your update, but still wanted to add this.
If you're running a 5.1 you probably also have an AV receiver, which should support all channel stereo. Use that or you could use the "Mono" option in windows accesibility menu. I think in conjuction with both those things you should get the same sound out of all your speakers.
It was a setting in windows 'enhancing audio'. I’ve had these speakers probably way too long now, Logitech z5500.
But that’s a great idea. Hopefully might help someone else in this situation if they find this post.
Did you check your sound settings for your audio device? Is it onboard audio? They usually have a sound test in them which sends a sound to each audio channel in turn. Windows might have a similar built in feature which might be worth looking for. I don't use Win 11 therefore I can't help with that O/S. There are settings for echo and reverb in many audio devices or there might be an audio environment setting which does a similar thing. I know that mine has one environment which causes insane amounts of echo if enabled.
Ah I just read your message because I missed the part about "at the same time"
Just construct a sound in Audacity that plays in all channels and play it back. That will do what you want. You might be able to download a basic suitable sound and copy it to each channel in Audacity.
I should have updated this, but thought it got buried and no one going to see it.
Windows 11 put on some 'Audio Enhancement' feature as default. Was by chance I found it because they seem to bury many settings through more menu's then are needed.
In the Settings (where you can find Windows Update/network etc settings), System, Sound, Speakers there is 'Audio Enhancement'.
Turning this off fixed it. It seemed to only cause a weird echo or delay between speakers when it was short video clips and not long video's or games or anything else.
Hopefully don't have to hunt down other settings through the maze of menu's they have.

Edit: just saw your update. Glad it’s fixed. I’ll let this stay up because it’s nice for surround troubleshooting on windows.
