i have the same (or not) issue.. but i don't report that here because i have another option
my situation is, if i play here on the laptop, the sound plays on the speaker
when i plug the headset to the headset port, the sound plays on the headset
the problem is when i plug my gaming headphones, it has usb cord, not the green plug like headset, so when i use t, other application switch the audio to the headphones but ff7 plays the sound on the laptop speakers.. haha
so when i play ff7, i use my headset, not the headphone
