Hmm, those calls eventually end up here, in audio_portaudio.c:

    349 int pa_select_devices (struct iaxc_audio_driver *d, int input,
int output, int ring) {
    350     selectedInput = input;
    351     selectedOutput = output;
    352     selectedRing = ring;
    353     if(running) {
    354       pa_stop(d);
    355       pa_start(d);
    356     }
    357     return 0;
    358 }
    359
    360 int pa_selected_devices (struct iaxc_audio_driver *d, int
*input, int *output, int *ring) {
    361     *input = selectedInput;
    362     *output = selectedOutput;
    363     *ring = selectedRing;
    364     return 0;
    365 }

so, I'm not sure how they could fail;  we don't even check that the
choices you give us are valid..

The only other place those variables are assigned to is in the
initialize method, which should only get called from iaxc_initialize().
