![]() ![]() Also, the number of traces through the ground plane should be as minimal as possible and they should not block the "line of sight" from the audio chip output to the op-amp to reduce total harmonic distortion (THD). It does not really affect me but it is just odd and kinda distracting. Does anyone know what might be causing this I have attached a video to show what kind of sound it is making. MSI says that its evaluation showed splitting ground planes between analog and digital components in the PCB is not really beneficial, and that the company recommends using only one ground plane for both the components to simplify the PCB design. I have recently bought an MSI GE66 and when I play audio, the speakers are making a weird noise. While we won't be getting into the nitty-gritty details here, it is considered good practice to not split ground planes in mixed signal PCBs, something that MSI also agrees with. Proper PCB layout is essential for quality audio output. Find release dates, customer reviews, previews, and more. ![]() The way in which analog and digital components of the board are routed to the ground plane can make all the difference in audio quality, as proper routing reduces electromagnetic interference and suppresses crosstalk.

For those not in the know, a ground plane in a PCB connects the board to the power supply ground. While factors such as the PCB stack, size, and onboard components are important variables, the key to a good audio chip performance, as with any PCB, is the ground plane. The PCB layout is a very critical aspect of headset audio component design and it helps to spend the extra time to ensure that a good electrical routing is achieved within the limited real estate.
