For a few months now, I've had an FiiO Olympus E-10 USB headphone amp. The reason for getting it was convenience; it allows me to just unplug the Thunderbolt cable from my MacBook Air and leave my headphones hooked up to the Thunderbolt Display through the E-10. The audio quality is actually quite good, but for some reason I get an audible click every time audio stops.
When a system sound has finished playing, there is a click
When I pause a YouTube video or when it ends, there is a click
When I play music from iTunes and a track pauses or ends, there is a click.
It's really quite annoying.
Additional data points :
When I have the headphones connected to my audio jack on the MBA, the click does not happen.
When I have another pair of headphones connected to the E-10, the click also happens.
No specific drivers were installed to support the device. None are available on the manufacturers site either.
In my view, all of the above appears to point towards a hardware issue.
Any similar experience?
Any thoughts on how to resolve it without buying a new device?
