I tried with many PCs but getting the same issue. I think the issue is with E17 itself. But I'm still wondering because it was working fine till last week and suddenly one day it is not getting detected. What happened in between? What was causing this issue? I don't understand
The last time when it was working fine, I was fiddling with 96 KHz/24 bit in Audio MIDI setup in my MAC os for HD tracks but thats the only thing which I did. But from next day it was not working. Even I tried to change back 96 khz to 44...
Fried Tenor chip most likely, by static electricity perhaps or maybe bad soldering. These amps are modular enough to be able to take a lot of punishment, so it might mostly still work. Sounds like RMA to me.
I hope FiiO switched their mail express company though, had some bad experience with it.
