Intel NUC8i3BEH sound buzzing 50Hz only when not playing and only after ca. 5-6s


Intel NUC8i3BEH running debian linux is connected to front 3.5mm jack to logitech sound system. The system is buzzing at 50 Hz when not playing. As soon as I click the play on e.g. youtube (on firefox), the buzzing stops and the sound is played correctly. When I pause the play by clicking the pause button on youtube, the sound is correctly silent for ca. 5-6 s, then the buzzing noise reappears (without touching anything at the cable...). It looks like something concerning the sound output is electronically switched internally in the NUC after 5 s. The behavior repeats constantly with the described actions. Please support on solving this issue. Thanks.

Hi ldamb,


This is a known Issue even on Devices using Windows(10).

Had the same with my NUC8i5BEH. Updating the drivers to the latest version has fixed it.

But I do not know the latest driver for Linux.


On Windows based devices it also helps using sound output via HDMI instead of the 3.5mm jack.
