Ok i built a headphone amp based off the:
http://tangentsoft.net/audio/cmoy-tutorial/
But i wanted to power the device with USB power as it is for my laptop and i hate buying batteries. Well it seems the USB is causing lots of noise (no music player). If i hook the same circuit but instead of USB power i use a DC adapter or 9V battery i get almost no noise so this is why i know it is the USB.
So do you guys know of of any good way to stop this USB noise issue or am i out of luck as it is the computer which has the issue?
Thanks
