Hi Brian,
The -1 and -2 are legit, pjsip uses those values to refer to default
devices. Your test code is probably getting an error returned from
pjsua_set_snd_dev, but then overwriting it with success (0) when you
call pjsua_get_snd_dev and it returns those default values. I would also
remove the call to snd_pcm_open and let pjmedia do it. Note that pjmedia
will iterate over various sampling rates to find one the device likes.
Regards,
Bill
