Question

我正在尝试从示例中运行streamutil.c和playfile但是我在运行它们时遇到错误。在运行streamutil时，我收到了这个错误：

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.

在运行playfile时，我收到以下错误：

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

19:08:35.706     playfile.c  Unable to open sound device: Unable to find default audio device (PJMEDIA_EAUD_NODEFDEV) [code=420006]

我经常搜索并尝试了很多解决方案，但没有一个能够解决问题。我认为我的音频设备有问题，但音频设备很好（用aplay-l等命令检查）。请有人告诉我该怎么办才能让它运行起来。

Ubuntu的解决方案是：

1-安装 libasound2-dev ：sudo apt-get install libasound2-dev

2-重新编译Pjsip包

解决了我的问题!!

从pjsip-app示例运行streamutil.c和playfile
