-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Aji, i dont know about your setup... first of all you need to know if the error is caused by YOUR Code or by compiling pjsip with the wrong options. Maybe you want to have a look at http://trac.pjsip.org/repos/wiki/Testing_Audio_Device_with_pjsystest But to your question, to add the code to list all detected audio devices in your system, you've to add the code #include <...> and so on (see http://www.pjsip.org/pjmedia/docs/html/group__audio__device__api.htm for the code) into you source-code file with the main() method.... compile and run. If you can't (or won't) compile on the target device itself you've to use a cross compiler, of course. Wolfgang >>>> dear pjsip support, I have installed pjsip in my development board(toradex vf61),it is successfully cross compiled and it is running fine, but when i try to make call it shows error like,.... **************** 18:39:21.728 pjsua_aud.c .Set sound device: capture=-1, playback=-2 18:39:21.728 pjsua_aud.c ..Error retrieving default audio device parameters: Unable to find default audio device (PJMEDIA_EAUD_NODEFDEV) [status=420006] ******************* Please help me to solve this problem. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAEBAgAGBQJU9ZzOAAoJECnqbQftp9NUDegQAJtc56GOv+M0zVc0ACr0VmbU hN5pxTqM/Wo4oVs+4NtXNIggoRxVxLVdCRWz0JcZsOMwus0x04Q8vbFFS+X16RWu jW8VkdmO3Hs4fmldYTJ1pwmMUEf2Fbx+SJ9USsdMRAVj5w94XrrP/KYC1/rqJTVV zlYUiaFCcIPWWoxCsRmvJdDOL+L1A8eo+nc44Ck+HyMjdgcFtDJTsAmP09xhg5U2 4DWIPMOGsU7oCBZTB0q176ldk0R4ZEdUUNCdkJ4zPac+vq74OLssUG9vftM/1qvm b5Gq66sor3lEs8PnspeS35g2R1VhphnZ1CfPwNO1yctH96Euc+oSpy8M1vO/Cppj GSFBAWHuRnpCPFUl8doHZ+ZpNfd6fLoRgO4M8ht+WXCKjClwo1EnFOtr/y2OYroc eG5BpWFo2cK9zW4fy9uHcP8pUKmPMx/rDzY/yDfYEvWXk6BpcKtHTCWMVVfXAqle LfrQRTk2VFkLIPH9PxWq9vG9JRKNcsLhWasyrC4Wl4huK1fvAB3SB3U7aO4FCNcR LpWHzaY3GdTfDHUXUvXvDRgICfshZL8E9kTrm+Qju7fd7H9Q90iZZ6BSOTtO4Wci bqAQkXnpTZjt1vRHgDPt+4m10OkYhkRMPlzHpvE4HFu7YuGOTrYZgL+nZBvCc0g/ +Q0T35mTYM0p0pz8IFNo =bQPl -----END PGP SIGNATURE-----
