FXSound plays sound for a split second after switching device then goes silent

Good evening.
My apologies for the delayed response, I was dealing with some bureaucratic nonsense…
Also, I’m afraid the best I can do, for now, is give you a link to a recent version of my first-aid-kit list of settings to check.
You can ignore the suggestions which obviously aren’t for you, like turning down the Effects sliders and trying LatencyMon.
Please post back and let me know if your problem persists after running through the list; if so, we can explore further options, and I will call in some help.
