A little more information for you Intel :
I try to play some video in youtube and the result it´s that not only the audio drop out but also the video freezes randomly,
so I think that it´s not only the audio wich are suffering drop outs but it´s all the system that´s suffering freezing.
So I start to think that the problem it´s more related to the RAM memory ...
Can you help to solve this big problem , please ...
Do you have the RAM in the top or bottom slot? (It should be in the bottom slot when using one module)
Are you overclocking the RAM? If yes, have you tried it at the stock SPD speed?
Does the whole system completely freeze up? Or just the video?
What brand of memory chips are on the Kingston RAM module? Hynix, Micron, Samsung?
If you run Memtest does it pass a few passes? MemTest86 - Offical Site of the x86 Memory Testing Tool
K24A3m has posted some good information we need to know.
Additionally, I have noticed that you are using Windows(R) 7, does it have the latest Service Pack? https://support.microsoft.com/en-us/help/14162/windows-service-pack-and-update-center
Does it happen with all of the USB ports?
Just had 4 days of RME UCX (USB) running on windows 10 without issue with stellar results. The only thing I found was that if you do use the charging USB port (yellow on the front) and have the BIOS setting disabled to allow that port to charge devices while the device is OFF, the soundcard wouldn't get recognized after boot - so I switched it back to allow charge, but switched to a different port anyway.
