Headphone toubles

[Amanita]

For audio I use a Schiit Modi DAC and Schiit Magni amplifier attached to some Beyerdynamic DT 770s, this setup is connected to my system via USB. For the past few months I have been having an issue where if my system goes to sleep and needs to be awoken by pressing the power button my headphones start making a very loud, constantly repeating sound. No other audio goes through the headphones, and turning the DAC/Amp off and back on again doesn't help. I can switch my audio over to the motherboard and it sounds fine, but when reverting to the DAC it keeps making the same noise,he only way to stop it is to restart my system. It only started recently, as I have been using this audio setup for several years now. Any idea what could be causing it? Here is a video with the sound the headphones make when I wake my computer, it isn't too loud in the video but it is almost unbearable if wearing the headphones. Please ignore my dusty mouse mat.

I find this odd as mine does that too, but i also have the problem where it disables my USB mouse when i switch it on. It also happens if its one before windows boots in. I just found this out after two years that it was my Modi causing this communication. I have been through 3 keyboards, 2 mice, 4 mothrboards and a handfull of wires to just turn on Modi while my computer was running (done this many times) and find my mouse get disabled. Drove me nuts. I switched the Modi off and the mouse came back.

I have a two corsair scimitar that i have this happen to. I find it odd that its the audio equipment where i find users with similar issues and not the mice or other equipment.
