Full names, okay, Bob Jones. Not sure I got the name tag correct, but will see after this post.
I plugged my sound system into the headset plug on front of my computer until my long cable arrives. If I boot with the plug there, I seem to lose the cockpit sounds. If I boot with the plug in the back port, all sound work correctly. Makes no sense to me, they should be the same. However, I did this twice with the same results.
