--- Comment #4 from Rajinder Yadav <devguy...@gmail.com> ---
Here is the output with a working FiiO BTR using the USB DAC Config setting:
1. FiioO BTR (hardware) set to Analog Stereo Output
2. Fiio BTR5 (headphone) set to OFF

=============================================================
Here is another output when the 2nd Fiio BTR5 device which becomes active after
a few seconds when the FiiO DAC is plugged is or Turned on. This causes the
audio to stop working as I showed in the attached pic and I have go and set it
to "Off".
Where ever the FiiO BTR5 (headphone) not set to "Off" after some time the audio
will just stop playing, this period seems to vary but eventually the audio goes
silent.
