If sound device is not initialized by application, PJSUA-LIB will
open the default sound device in pjsua_start(). If you want to use
no device (that is null sound device in pjsua's term), then call
pjsua_set_null_snd_dev() before calling pjsua_start().
In pjsua, you can set pjsua to use no device with --null-audio option.
