Running with root privilegies, the warning went away:
14:18:12.516 alsa_dev.c !ca_thread_func(2765): Set thread priority for audio capture thread.
14:18:12.517 speex !warning: discarded first playback frame
14:18:12.521 speex warning: discarded first playback frame
14:18:12.524 speex warning: discarded first playback frame
14:18:12.526 speex !warning: discarded first playback frame
But the speex warning continues.
In my code, I have this callback function defined:
static void on_call_media_state(pjsua_call_id call_id) {
pjsua_call_info ci;
pjsua_call_get_info(call_id, &ci);
if (ci.media_status == PJSUA_CALL_MEDIA_ACTIVE) {
// When media is active, connect call to sound device.
pjsua_conf_connect(ci.conf_slot, 0);
pjsua_conf_connect(0, ci.conf_slot);
}
}
The connection with pjsua_conf_connect, shouldn't be with the frames after being processed by the aec?
Thanks.

Oh, ALSA dev. I don't have much of any experience with this, but it is a frequent topic on the list. You might want to browse through the archives. I note the following in the log:

If the audio thread priority isn't high enough, you could get underruns which would cause the speex warnings you see.
