Today I picked up a Fiio E07K + E09K for my Q701s and tested it. I had all the settings right for Foobar and windows and it worked perfectly until about 30 minutes after;
There was no sound coming out of the headphones. Whenever I try to play a file I get this error: Unrecoverable playback error: Incorrect function. (0x80070001)
But if I switch out the settings in foobar in the playback output from E07K to the speakers of my laptop it works fine. I don't want to play my headphones through the laptops headphone jack.
Any help will be greatly appreciated!
