Unable to use Earbuds with FXSound

Good afternoon SarcasticWriter,
As usual, my first line of defence is a repost of my first-aid-kit list of settings to check first, which you can find here.
Please try checking those settings first, and let me know if anything improves.
If your problem persists, I will, as usual, call in the assistance of FxSound’s lead audio engineer, @bvijay.
