Hi, I've a pjsip stack installed in a Samsung Q1 Ultra (with Ubuntu) and I start pjsua with the following options (with a config file): # # Logging options: # --log-level 5 --app-log-level 4 --log-file pjlog # # Network settings: # --local-port 5060 # # Media settings: # --capture-dev=1 --playback-dev=1 --playback-lat 100 --clock-rate 8000 #using default --quality 10 --no-vad #using default --ec-tail 200 #using default --ilbc-mode 30 --rtp-port 5000 --add-codec pcmu --dis-codec speex --dis-codec ilbc --dis-codec GSM --dis-codec G722 # # User agent: # --max-calls 4 # # Buddies: # So, I force the clock rate at 8000 Hz because I've the other endpoint, working with the stack, sending an audio with PCMU codec at 8000 Hz. When I launch pjsua in Q1 I obtain some warnings like following: pjsua_media.c pjsua_set_snd_dev():attempting to open devices @8000 Hz pjsua_media.c ..failed: Invalid sample rate and the same for devices @22050 Hz and @44100 Hz The same pjsua on my desktop machine don't log these warnings... If I set as Capture and playback device an USB headphone set there are no problem. the problem is the sound card don't supporting the 8000 Hz sample rate? Cheers Emanuele
