For receive, data from the receiver goes to the E-MU 0404 USB at ~10 KHz where it is digitized then processed by the application and comes out the speaker as audio - that works at 48K, 96K and 192K sample rate. For transmission you speak into the mic and it's processed by the application, digitized and sent to the E-MU 0404 USB where it's converted to audio that is used to modulate the transmitter and out to the antenna - that doesn't work even at 48K sample rate, i.e there is no output from the E-MU 0404 USB. . >>>>> dmesg output with 48K sample rate set is:- >>>>> ALSA sound/usb/clock.c:214: 6:2:3: endpoint lacks sample rate attribute bit, cannot set. > > There are many devices that have only one sample rate or that have one > sample rate per alternate setting.
