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:- [509686.177169] ALSA sound/usb/clock.c:214: 6:2:3: endpoint lacks sample rate attribute bit, cannot set. [509686.187920] ALSA sound/usb/clock.c:214: 6:2:1: endpoint lacks sample rate attribute bit, cannot set.
