Hi guys, Does anyone know how to release sound device on symbian platform, I use VAS. Here is the scenario: I have implemented a sip application using pjsip. When I have one VoIP call on hold and then a normal GSM call is incoming, I want device to play the profile's ring tone. I find if I can release sound device, the phone will play the ring tone correctly. I try to use pjsua_set_null_snd_dev to release the sound device, but get error message pjsua_media.c Unable to create null sound device: Unknown pjlib error 70012 [status=70012]. Error 70012 means PJ_ENOTSUP--The specified option is not supported. Dose anyone know how to use pjsua_set_null_snd_dev API. Should I call some other function before call it?
