this breaks it. after the sndio conversion nothing works; no input detected, and output also fails. to test: go through the basic setup - you need to choose your audio device, but can ignore the macros. after this it goes to the main screen in receive mode; this should have a scrolling spectrograph, and a waveform display, showing the audio input. switch to transmit mode (ctrl-t, red coloured button) and type into the bottom text window, it should output audio. it's a simple software modem; half-duplex - no handshaking etc. to test that it's working you can just record the output audio and play it back into receive mode, you should see your text played back. you shouldn't need anything really fancy, in the absence of having any better equipment handy I'm just playing it back over headphones turned up high through a laptop microphone, and even that is working for me with the old version (you would expect these modes to be quite robust, some of them in particular are used for low-power long distance radio comms and are very robust to certain types of distortion/interference).
