Thanks Kevinwal , when I opened win 10 performance monitor and selected dpc rate and dpc time they were very consistent with latency mon so thanks for confirming my thoughts .
Anyways I did a update last night I loaded a usb flash drive with win 10 on it , I then repaired Windows keeping all my programs and it reset Windows completely , along with Andertons AMD driver update I knew this morning as soon as I fired up the pc that the problem was gone , the gritty on the edge feeling in my ears that it's going to drop out any second , every second was no longer there , I have been using it all day for the first time in 2 weeks without a single drop out , I know this is fixed I can tell how smooth it runs in my ears ,so hopefully I'm right .
Thanks everyone I am thinking it was the amd drivers so thanks mr Anderton again .
I will post if the problem pops up but I am sure it's gone like I said I can hear it's gone ,
Regards
