So been using my Fiio E17 lately on my Macbook pro 17 inch unibody (not retina). Everything plays well, except when I press on a key, I hear static / cracking sound for a few seconds. The static / cracking sound comes back when I press any key on the keyboard.
At first, I thought it was the headphones, or something loosely connected. So I plugged the headphones (Hifiman HE-400) directly into the laptop. NO PROBLEMS.
I suspect, he issue was with the amp / dac. Funny thing is, if I plug the amp / dac into another USB port, the static / cracking sound issue does not come up. Either it's the amp / dac or something wrong with the USB port in my laptop.
I am using Lion 10.7.4. Will upgrading to Mountain Lion fix this issue?
Anyone experiencing the same problem?
