R770 loud coil whine

[solstice]

Hi, about 6 months ago I purchased some R770s and installed them in my home with 10G POE via a Netgear MS510TXUP. While it’s been some time since I’ve owned them, I’ve finally gotten around to making an account to ask about the extremely loud high-pitched coil whine I hear when being around them (<20ft). Has anyone else encountered this? Could this be addressed with new firmware, or do I need to switch to another brand?

Thanks
