switch to loudspeak in e61

[reuvenb]

Hello,

I want to switch the sound to loudspeaker in my application.
I saw lots of post about this issue but none of them works for E61.

I've tried this code of aps:
TInt errNo = RProperty::Set(KTelephonyAudioOutput, KTelephonyAudioOutputPreference,EPSPublic);
and it's working fine just for n95. not for E61.

I've also tried this two options:

1. CCallAudioControl* iAudioControl= CCallAudioControl::NewL();
TInt retVal = iAudioControl->SetOutput(CCallAudioControl::ELoudspeaker);

2. RAPSSession iSession;
TInt err = iSession.Connect();
iSession.ActivateLoudspeaker(ETrue);

Both options returns "unable to install" message while I was trying to install the my application.
What is the solution to activate the loudspeaker for E61?

Unable to install is propably coming from something very different reason that what is written in your code, so check what the actual conflict is..

Both 1) and 2) are private plugin APIs. Did u first install the sisx file that came with the API's? If you havent, try installing them first before installing your app.

API plug-in do not usually require installing any additional sis files into the device, exceptions being APS of course.
