We have been using a Qu-24 at church for around 6 months and today was the first time that an audible sound is heard on the mains every time that the Qu drive is accessed. I have tried powering the mixer off, moving the cables away from the mixer and using another drive, but is still prevails. Here is a short clip of the noise heard:

We upgraded to v1.9 a few weeks ago but it is the first time that this happens. I do not know if it is related, but previously we had a case where the drive was not detected and the led only flashed very dimly. Rebooting the mixer helped. This happened right after upgrading to v1.9
Do you have idea what could be done to fix this?
