m15 R5, buzz sound
Alienware m15 Ryzen Edition R5
Hi,
This is my new computer. I found buzz sound when I open, do/run a project on a software like "Unity" or "Unreal Engine". I don't know why there is buzz sound, where it comes from, or how to solve this problem? Any suggestions/advices, I would be appreciated.
Thank you so much:)

It sounds as though your laptop has what is called "coil whine".
Essentially, coil whine is the audible effect of components vibrating, especially when under high load / high power. It can sound like a whine, buzz, hum, scratching, hiss, rattle or vibration. This happens with many components, but often it's not loud enough for us to hear or at a frequency that we don't hear well.
These two pages have more explanation and some tips to reduce the effect:
Unfortunately, you may not be able to eliminate it to your satisfaction. Much depends upon how you use your computer, the acoustic qualities of your room, other ambient noise, etc.
Coil whine can occur with brand new components. Components that were previously quiet can develop coil whine as they age. It has also been reported that certain software (usually games) that draw a specific power load can cause an inductor to vibrate at a specific frequency that is audible.
I once had a Netgear router whose coil whine was particularly annoying to me. I found that the volume varied among units of the identical model. I tried two or three other units of the same model in the store, and found one that I couldn't hear. Even though they were the same model, same components and power supply, two or three of them were loudly annoying to me, but the last one was inaudible.
As crimson advised, if you are in the first 30 days since the laptop shipped, you can request a return and refund.
