I have an application using the on-board sound card mic which should
send it's data to the USB card for relay to a Sofweare Defined Radio as
2 quadrature signals digital (I/Q) for transmission.
On the receiving side it can take data from the Radio at up to 192K
sample rate --> program --> Speaker on the on-board sound card - that
works fine.
Transmit fails, dmesg output with 48K sample rate set is:-
