Hello, I am trying to run streamutil.c and playfile from samples but i am getting the errors on running them. On running streamutil, I got this error: 19:07:43.822 os_core_unix.c !pjlib 2.1 for POSIX initialized PJLIB INIT COMPLETE 19:07:43.825 pa_dev.c PortAudio sound library initialized, status=0 19:07:43.825 pa_dev.c PortAudio host api count=1 19:07:43.825 pa_dev.c Sound device count=0 19:07:43.825 pjlib select() I/O Queue created (0x7c87b8) a.out: ../src/pjmedia/codec.c:53: pjmedia_codec_param_clone: Assertion `pool && src' failed. And on running playfile, I got the following error: 19:08:35.703 os_core_unix.c !pjlib 2.1 for POSIX initialized 19:08:35.705 pa_dev.c PortAudio sound library initialized, status=0 19:08:35.705 pa_dev.c PortAudio host api count=1 19:08:35.705 pa_dev.c Sound device count=0 19:08:35.706 pjlib select() I/O Queue created (0x13db7b8) 19:08:35.706 wav_player.c File player '/home/udit/pjsip/alarma.wav' created: samp.rate=22050, ch=1, bufsize=4KB, filesize=265KB 19:08:35.706 playfile.c Unable to open sound device: Unable to find default audio device (PJMEDIA_EAUD_NODEFDEV) [code=420006] I have searched a lot in the lists and tried many solutions but none them worked. I thought there is some problem with my audio device but audio device is fine(checked with some commands like aplay-l, etc). Please someone tell me what should I do to make it run.
