If your Samsung Chromebook 4 Plus XE350XBA-K05US is not making clear sound, has buzzing, or just is not producing any sound at all, you may need to replace the internal speakers. These internal speakers are what allow you to hear sound from your Samsung Chromebook, so when they stop working properly, the audio can be distorted or completely gone. Replacing the speakers is the best solution.
Before starting, check for dust or debris in the external speakers, and test with headphones to make sure the problem is the internal speakers and not the hardware. If the problem is the hardware, then this may not be the guide for you. Once you are certain it is the speakers, power off your Chromebook and disconnect it from any power source. Make sure you are working on a clean surface.
Important Tips:
