I have an Asus laptop that I'm using to send music to my Little Dot DAC_1/MKIII/650 combo. I've noticed that there is noise, and some times quite obtrusive even with loud music, coming from the computer. I stopped the music and unplugged the AC from the laptop and let it run on battery. I turned up the amp to max and it was absolutely dead silent. Plug the AC back in, and so starts the hideous buzz. The LD DAC_1 is powered by it's own cord and not powered through USB, I just have it set up to use the USB as a means to retrieve the music. How would I go about fixing this problem, if I can? My battery only lasts for about two hours, and I listen for quite a bit longer than that.
