usb microphone and hdmi out - no audio on hdmo

hi

i got this microphone mxlmics.com/microphones/web-conferencing/AC-404/ MXL AC-404 for voice control, but it also has a headphone port on which tells the os to send the audio stream to usb. I need to send audio to hdmi stream as it tv box. I tried setting media to aux but hdmi is still muted and i only get video or headphones output, but if i set media to bluetooth its work, both mic and bluetooth audio. Let me know if you have any suggestions, thanks.

Sorry,I finally have some time to answer some questions on the board.

Try the latest Beta.  There is new widget called "USB Mic Toggle".  This will send ONLY the USB input signal so that the audio can be send to a different audio output.
The icon and text for this widget are fairly straight forward.  Try putting that widget on the home screen and testing it with your USB microphone.

Let me know how it works.
