I'm using APS 2.31 on Nokia E61. I need to play a sound down the active phone call. I don't need to record. I am a platinum partner and have multimedia DD.
If I set up the audio proxy server using code similar to the example loopback application, I can successfully play audio and also record phone calls. The code seems a little unreliable though - if I run my server twice in succession, quite often the second instance will hang when setting up the APS recorder.
Specifically it will hang in code like this:
(this code is taken from the Nokia example).
If I take the same code and remove the calls to set up the recorder, the application makes no sound! Does this API only work for apps that both play and record? The documentation seems to suggest otherwise.
Finally - at the download for the APS zip, it is marked as "This resource is archived because it is not considered relevant for developers creating commercial solutions today. The resource is believed to be still valid for the original topic scope". Is this true? I have had no luck using any of the very many Symbian APIs for audio playback - whichever magic numbers I use for audio priority and preference.
