When using the built-in GPU, there is a coil whine sound.
The issue appears to be related to how the graphics card communicates with the motherboard via HDMI. It seems the coil whine occurs only when using HDMI from the motherboard port, not the display cable, suggesting a problem with the HDMI connection or driver handling. When integrated graphics are off and the HDMI is used through the motherboard port, the noise disappears, indicating the problem is tied to the external HDMI setup. You can likely fix it by ensuring the HDMI cable is properly connected and using the correct port, or by updating the graphics drivers.
