Well done that is brilliant news. Looking forward to seeing how this was achieved, wonder what I missed :-)
This is a great step forward to be able to use a USB headset, especially after investigating the fault on my supplied fist mike. 2 of the wires from the cable had become disconnected from the 3.5mm stereo plug, probably due to the lack of strain relief on the connector, not great for portable operations so the USB solution will be a big improvement in that regard.
looks like changes are on the way ... let's stay tuned ... ? -- Pete VK3PYE
I am happy to announce that I have successfully routed USB speaker audio AND USB microphone audio to the sBitx using my 64 bit beta 2 build. I am currently building an app for this and will share it when ready for the masses.
