Hey! I have my headphones plugged into my speakers and when I turn on my PC, the sound source changes to something else, which of course doesn’t give me any sound. Is there any way to save the sound source, so that FXsound does not change it for some reason?
Have you tried disabling automatic switching in the settings menu?
Disabling unneeded/unwanted sound devices in the Windows Sound Devices settings is another way to prevent unwanted switching. Often, Windows (or the graphics drivers) add your monitors to the list when they support audio over HDMI, for example.
