Hi Michael,
Make sure the server-side audio is set to the radio’s audio device. It might be called something like alsa_input.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00.analog-stereo. There will be one input like this and one output. If the server-side is set up like this, then you should hear the audio.
At the client side, your configuration looks correct. You’ll want to make sure that you have access to ports 50001, 50002, and 50003, as wfview uses all three (UDP).
Lastly, set your Modulation Input to “USB” for both data and non-data modes.
You’re close. Let us know if that works.
