When experiencing the noisy audio issue with the chassis front panel audio port, please cross testing with the chassis and the motherboard to troubleshoot the source of the issue since the audio signal is transferred from the motherboard jumpers.

If the noise occurs with the motherboard I/O audio port, please send the motherboard back to MSI authorized service center for testing. However, if the issue occurs with both the chassis front panel and the motherboard I/O audio port, it is recommended to uninstall the existing audio driver and install the latest audio driver released on MSI official website.

If the problem persist, we would suggest you to cross testing the external speaker before sending the motherboard back to MSI authorized service point.
