When either listening to music, watching a movie, viewing Youtube on Chrome, using *any* application, if I have Simultaneous Output enabled, the resulting audio output is generally delayed on one sound card from the other, and I cannot seem to find a viable way to fix this.

All speakers are equally far from the user, so the speed of sound travelling has nothing to do with this to my best estimations.

What could it be that is causing these issues?

Attached is a HardInfo report of my Ubuntu PC.
