Hi, I tried to run pjsua on enbedded linux( Armadillo-220 ) with USB audio device. Error message "Invalid sample rate" occurs when I test --play-file as follows. ------------------------------------------------------------------------ ./pjsua-arm-unknown-linux-gnu --play-file /mnt/nand/DBaloon.wav >>> cl Conference ports: Port #00[16KHz/20ms/1] Master/sound transmitting to: Port #01[16KHz/20ms/1] /mnt/nand/DBaloon.wav transmitting to: Port #02[16KHz/20ms/1] ringback transmitting to: Port #03[16KHz/20ms/1] ring transmitting to: >>> cc 1 0 12:26:12.300 pjsua_media.c pjsua_set_snd_dev(): attempting to open devices @16000 Hz 12:26:12.331 pjsua_media.c ..failed: Invalid sample rate 12:26:12.332 pjsua_media.c pjsua_set_snd_dev(): attempting to open devices @44100 Hz 12:26:12.362 pjsua_media.c ..failed: Invalid sample rate 12:26:12.363 pjsua_media.c pjsua_set_snd_dev(): attempting to open devices @48000 Hz 12:26:12.393 pjsua_media.c ..failed: Invalid sample rate 12:26:12.394 pjsua_media.c pjsua_set_snd_dev(): attempting to open devices @32000 Hz 12:26:12.423 pjsua_media.c ..failed: Invalid sample rate 12:26:12.424 pjsua_media.c pjsua_set_snd_dev(): attempting to open devices @16000 Hz 12:26:12.454 pjsua_media.c ..failed: Invalid sample rate 12:26:12.455 pjsua_media.c pjsua_set_snd_dev(): attempting to open devices @8000 Hz 12:26:12.485 pjsua_media.c ..failed: Invalid sample rate 12:26:12.486 pjsua_media.c Unable to open sound device: Invalid sample rate [status=269996] 12:26:12.486 pjsua_media.c Error opening sound device: Invalid sample rate [status=269996] ERROR!! ------------------------------------------------------------------------ playfile log is as follows.
