[Linphone-developers] Sound Volume in iPhone When Using G722 Audio Codec in iOS 6

[powerqian]

Hi,

I found out that when the iPhone client only uses the G722 audio codec, the
sound volume will be very soft, especially using speaker. 

This issue only happens in iPhone, with iOS 6. In iOS 7 the sound seems to
be much louder.

I tried to apply the playback gain but the sound quality will be worse.

Are there anything in the linphone library might cause this problem?

Thanks.
