Hello, I'm currently using a FiiO E09k with an E17 on my computer. Recently, it suddenly started making a popping static-like noise every few seconds in my left ear. I tried using my headphones on just my computer without the amp/dac and it worked fine. I then tried using the amp/dac on my laptop and still heard it. I tried taking the E17 out of the E09k, and plugged my headphones into just the E17 and I heard it again. So I narrowed it down to the problem being the E17 itself. Anyone else have or had this issue?
