I guess I can just turn off the monitor as I'm using RDP anyway and controlling everything from the laptop.
I have a sketch of a HDSDR plugin
and a tiny server to run on an Android phone, so you don't need to run a laptop.
to stream the Softrock RX IQ output onto a local network. Currently it works only with an Peaberry SDR aka Omnia Basic. There is no official support for direct access to USB sound card on Android, one has to implement an USB sound card driver in user space oneself. However I am considering to try to add a support for Behringer UCA222, which is based on PCM2902. This chip work similarly to the USB interface of the Peaberry, it locks to the 1ms poll interval of the USB interface, thus the interface is simple to implement, at each USB frame the same number of bytes is handled.
