Sometimes I can hear some sort of low noise from the loudspeaker, even if no App is running.

When this happens you can not change the ringtone volume with the volume rocker, but instead control the playback volume with it (which does not change the volume of the noise, nor is there any app that could be controlled).

The only way to get rid of it, is to stop (and restart) the Android compatibility layer or reboot the device. After that the noise is gone and the volume rocker controls the ringtone volume correctly.

I didn't check the impact on the battery, but I think this bug causes some battery drainage because the loudspeaker makes the noise permanently.

Did you check if an android app is still running in background (with an app like Memory, Crest or Lighthouse? In my case, VLC stays active once I played a video in WhatsApp. Opening and specifically closing VLC helps in this case

Good suggestion! I will check this the next time it happens. Thanks! On the other hand, this never happened on the Jolla 1 (or the noise was not hearable?!)

Might be due to lower quality "soundcard". I have a similar issue on my Thinkpad X240: I can hear a static noise when an audio channel is opened but nothing is played. Never had such an issue on my previous notebook...
