    I have a USB Headset, Keyboard, and mouse plugged in to my PC. When sound is playing my mouse works but pressing any key on my keyboard will make the disconnect/connect sound. But when there is no sound playing my mouse and keyboard both work fine. how can I go about fixing this?

    What is the brand and exact model of computer? How many USB ports does the computer have?
    My thoughts are there is not enough power supplied by the 3 ports to allow the 3 devices. (I don't own USB headset and only 1 computer in the house uses a USB keyboard and mouse so I can't test).
    Since the USB headset might be drawing too much power, have you considered using a headset with a 3.5mm plug instead?

    Power or a faulty device would be my guess. There is no realistic limit to the number of USB devices that can used (the OS supports many more devices than the number of ports on any computer).

    You could try using a powered USB hub (hub with an AC adapter). Then the power used would be supplied by the hubs power supply and not the computer. I would recommend, however, keeping the mouse and keyboard connected to the actual computer and only use the hub for other devices.
