Thanks for your reply.

Sorry, I forgot to mention that the noise starts almost immediately after switching on the Pinebook. First the orange light turns on and after 4 seconds the noise starts when the LCD backlight turns on. That`s right before u-boot starts. So that of course is before the eMMC or SD card is being mounted. This seems not to be dependent on the boot medium or OS and this is even when booting without any SD or eMMC.

So if that's sofware related then probably u-boot causes it. But I made no update of u-boot since installing the OS in August this year.
