M3 lite 10.1 external speaker crackling/distorting sound

[daigs]

Hi to all,
I just bought a M3 lite 10.1 and in some hours discovered an annoying defect that I please ask you to confirm or not in your device.

When music (from youyube or internal mp3) is playing on the internal 4 speakers at a medium to maximum volume and one try to close partially the holes' speakers (the lower or the upper one) the sound start to crackling like a distortion. It appears as a internal membrane starts to vibrate. If the speaker holes are free the problem doesn't appear. If the speaker holes are completely close the problem doesn't appear and the sound obviously doesn't output. The problem is more audible with music without drums like this:

This crackling/distortion is very annoing beacuse in landscape mode the tablet is always in position in which the 2 lower speaker are with the holes partially close... so the distorsion is inevitable.
I searched on all the forum but I did not read any about this specific problem on M3.
Anyone with the same problem? Any solution?
Thanks.

Can someone help me testing in his M3 lite 10.1 device if the defect above described appears with the video provided or similar with piano or guitar solo?
This could avoid to call the assistance if the problem appears on all M3 devices.
In the title I mean "internal 4 speakers"
Thanks a lot.
