People producing a sharp, high-pitched noise
Your audio setup is producing a high-pitched tone similar to the clip you mentioned. At maximum volume, it creates a buzzing effect. The speakers you're using appear to be Logitech Z130 models. Let me know if you need further assistance.
It seems like RF interference is likely the cause. (Probably RF interference.) Usually, the auxiliary output can have this problem. This happened with my 2008 RAV4. Using an online resistor often fixes it.
