Actually i dont think its internal PC problem but i have Win10. The BlasterX card model is G1, also i use a potentiometer for audio which has exposed circuitboard and its plugged into that BlasterX card. And the speakers are some old SurfSound 120W. And after plugging in it looks like the BlasterX is disconnected And Groove music says: We can't find an audio device. Make sure headphones or speakers are connected. For more info, search your device for "Manage audio devices.". I also found out that when i plug in charger or other plugs in socket extension it happens too ( the speakers are plugged in extension ). There might be induction in all that cables or something.
