Hi Julian and Steven,

Thanks for the suggestion. I tried it by altering the Audio Session handler in 
CsoundObj.m and testing it on an iPhone but the sound level remains the same. 

In case I missed something, here are the relevant changes I tried to make. 

I'm happy to test any other suggestions you care to offer. 

Version 5.18 will be a giant leap if we at least know how to route sound to speakers 
- if only for those whose sound world is not trapped in an iPod :-)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

/* Audio Session handler */

AudioSessionInitialize(NULL, NULL, InterruptionListener, &mCsData);
AudioSessionSetActive(true);

// Julian's suggested fix

UInt32 doChangeDefaultRoute = 1;
AudioSessionSetProperty(kAudioSessionProperty_OverrideCategoryDefaultToSp
eaker, sizeof(doChangeDefaultRoute), &doChangeDefaultRoute);

// reinstated comments

//        UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker;
//        AudioSessionSetProperty (kAudioSessionProperty_OverrideAudioRoute, 
sizeof(audioRouteOverride), &audioRouteOverride);

// other properties defined by the Audio Session handler

etc

output is through the headphones or earpiece (as if on a phone call), which is 
much quieter than the speaker at the bottom of the unit.  Here's the property to 
change that:
