我使用PJSIP PJSUA API开发iOS VoIP应用程序。我成功地编译了PJSIP iOS库，并成功进行了注册。但是，当我启动呼叫时，我会收到以下错误：

19:52:39.821            pjsua_aud.c  .Set sound device: capture=-1, playback=-2
19:52:39.821            pjsua_aud.c  ..Error retrieving default audio device parameters: Unable to find default audio device (PJMEDIA_EAUD_NODEFDEV) [status=420006]
19:52:39.822          pjsua_media.c  .Call 0: deinitializing media..

我查找了一些信息，例如设置空设备：

pjsua_set_null_snd_dev();

这确实成功了，但是没有声音。我知道这仍然是因为我没有获得音频设备。我该怎么做才能成功获得音频设备？

I used PJSIP PJSUA API to develop iOS VoIP applications. I successfully compiled the PJSIP iOS library and registered it successfully. However, when I initiate a call, I get the following error:

19:52:39.821            pjsua_aud.c  .Set sound device: capture=-1, playback=-2
19:52:39.821            pjsua_aud.c  ..Error retrieving default audio device parameters: Unable to find default audio device (PJMEDIA_EAUD_NODEFDEV) [status=420006]
19:52:39.822          pjsua_media.c  .Call 0: deinitializing media..

I looked up some information, such as setting up an empty device:

pjsua_set_null_snd_dev();

This did make a successful call, but there was no sound. I know it's still because I didn't get the audio equipment. What can I do to get the audio equipment successfully?
