Hi all. I have had the Fiio E17 since the beginning of this year, and this issue started to occur about six months in. I have searched the forums, but the other static issues people are having are not the same as what I am having.
I use the E17 via USB, and have found that after I leave the amp connected with no sound playing for a while, when I start playing sounds/music from it again, the sounds will have a lot of static. The longer I leave it idle before I start using it again, the worse the affect is. Depending on how long the amp was left idle (no sounds playing), it ranges from slight static/scratching over the sounds being played, to inaudible sounds where you hear nothing but light static/crackling. Sometimes you will see "LOCK" constantly appear and disappear as if it is having trouble getting a signal. To fix this, I must unplug and re-connect the USB cable.
I have determined that this isn't an issue with the headphones, which was probably obvious already, and I have tried to use a different USB port and experienced the same issues. Has anyone else had this issue? Is there any explanation as to why this may be happening? What else can I do to troubleshoot this and resolve this? I played with idea that perhaps coupling the Fiiowith the E17 would stop these issues, but without knowing for sure what is causing the issues in the first place, buying the E09K may be pointless.
