[pjsip] playsine does not play on symbian

Cool! At least now I know that it will really play sounds.

We can't play full duplex because Nokia says so. Full duplex is only accessible with some sort of special license from Nokia.

I forgot why we need CActiveSchedulerWait. I concluded that from reading Symbian docs.

Hi Benny,

Thanks a lot for quick and help ful reply. We here also were able to get 
events now, to do the same I start a nested Schedular in 
CPjAudioOutputEngine::StartPlay (Symbian_sound.cpp), creating 
CActiveSchedulerWait as class variable and then starting it. Were able to 
play sound by providing a providing a wav file as buffer.

So after this symbian ua menu is showing up on device!  Why do you think 
we can't do full duplex? 

I have a question regarding use of CActiveSchedulerWait  in 
main_symbian.cpp, Did you have any specific use which installed 
ActiveScheduler won't do?

Regds

I did some work into Symbian sound couple of weeks back, and at
least I saw the callbacks being called (after some bug fixing, of
course!).

Check out the latest SVN trunk, it now has a separate sound test
program for Symbian (symsndtest.mmp). I haven't tested anything like
playing sounds yet, so it may still not play sine waves, but maybe
you'll get better result. But one thing for sure, full duplex audio
doesn't work on S60 3rd edition.
