I am creating an application that plays and record sounds simultaneously.
Im using CMMFDevSound for recording and CMdaAudioPlayerUtility for playing audio. It was running very well but when I tried changing the volume while playing and recording, the audio produced was reduced 10 about 20-30% of the setting.
Vol -> 5
When the player and recorder starts the sound produced was ok.
Changing volume to 6
the audio produced was as loud as the volume setting for 2.
I think the changing of sound is working since if I increased the volume it produced louder sound and if I decreased the volume the sound produced it also decreased.
It seems that the sound was at the background.
Can anyone help me with this?
