This enclosure can generate the same buzz when the sound is muted

However, this speaker is very susceptible to interference with the monitor power son for whom it is recommended (Dell U2414H)! This then produces a permanent modulated hum on the left channel, even when the sound is muted. After several tries, I finally found a configuration that does not generate noise. This is a design flaw that can and should be treated by Dell.

Once this Treaty, it remains a very light breeze, identical on 2 channels, which remains acceptable. In a quiet environment, we must strain to perceive it.
