Solution 1

This code should be useful for you:

#import <AudioToolbox/AudioServices.h>

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

It will increase volume. The functionality of the code is to convert the ordinary sound to speaker sound on ur iPhone. That's why kAudioSessionOverrideAudioRoute_Speaker is used.

Solution 2

Since iOS7 you can fix this issue directly with AVAudioSession

The overrideOutputAudioPort method does the same than AudioSessionSetProperty

NSError *setOverrideError;
NSError *setCategoryError;

AVAudioSession *session = [AVAudioSession sharedInstance];
[session setCategory:AVAudioSessionCategoryPlayAndRecord error:&setCategoryError];

if(setCategoryError){
    NSLog(@"%@", [setCategoryError description]);
}

[session overrideOutputAudioPort:AVAudioSessionPortOverrideSpeaker error:&setOverrideError];


if(setOverrideError){
    NSLog(@"%@", [setOverrideError description]);
}

Solution 3

Swift version :

 import AVFoundation
 var overrideError : NSError?
    if AVAudioSession.sharedInstance().overrideOutputAudioPort(.Speaker, error: &error){

    }else{
        print("error in overrideOutputAudioPort " + overrideError!.localizedDescription)
    }

Swift 2:

        do {
        try AVAudioSession.sharedInstance().overrideOutputAudioPort(AVAudioSessionPortOverride.Speaker)
        } catch {
        }

Solution 4

The following code fixed this issue for me:

[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayAndRecord error: nil];
[[AVAudioSession sharedInstance] setActive: YES error: nil];
UInt32 doChangeDefault = 1;
AudioSessionSetProperty(kAudioSessionProperty_OverrideCategoryDefaultToSpeaker, sizeof(doChangeDefault), &doChangeDefault);

I tried using AVAudioSession and AVAudioPlayer to record and play sounds respectively but the sound volume is very low.

I tried putting volume value of AVAudioPlayer to 1.0 and more but didn't help much.

What could be my other options to record sound which can be loud enough to play back?

Thanks for the input. I will check it out and get back to you soon :)

Thanks a lot this did work :) I was in search of a solution to this since a day now.

Don't forget the import statement. Perhaps obvious for the more experienced programmers... #import <AudioToolbox/AudioServices.h>

I added that to the answer above, thanks for mentioning the import required.

I got it to work (the sounds comes out of the speakers), but I'm not sure if I'm using it correctly. Is this a one-time thing at app-launch? Once at viewDidLoad for my controller? Once every time I make a new AVAudioPlayer? As KKendal asked: where does this go? Thanks!

Your code works just fine :) but it is now deprecated since iOS7. Please see my answer below for an updated solution.

With Swift 2, this is now a do-try-catch situation, no need for overrideError optional

this line saved my life, thanks man [session overrideOutputAudioPort:AVAudioSessionPortOverrideSpeaker error:&setOverrideError];
