I've somehow managed to solve the issue myself.
I'm not really sure how, all I did was click around in the sound and device settings, disabling and re-enabling things like spatial sound, switching from stereo to surround and back to stereo, etc. I did these things yesterday and they didn't work, but apparently my laptop decided that was good enough to fix it today! Great!
Thanks to anyone who read through my question, and if anyone has any input into what exactly might have been happening, it would still be appreciated.
Thank you.
So, today (04/01/2020), I experienced this exact problem as well. I also managed to correct it. To add any insight to others who might come across this problem, the only thing I did that had an affect and fixed this problem was change where I had my headset connected to.
More specifically, I have an Arctis Steel Series 5 headset, connected via USB. I did some work on my rig yesterday and plugged my headset into a different USB port. Only DAI was affected, and I have no idea why. Switching back to the original USB port corrected the problem without restarting the system.
