Motherboard is a Gigabyte GA b150n updated the latest realtek audio drivers. Even tried older versions to see if that helped. All Audio devices that get their audio from the mobo keep cutting in and out intermittently - tried both speakers and headphones from the 3.5mm jack on both the front and rear, also headphones through USB. When it disconnects the system momentarily does not see the device. My guess is that this is a problem with the mobo itself but pretty clueless about audio so defering to advice here.
