I'm developing VoIP application using low latency fast path,the problem is that when I change the audio route to speaker I noticed that the recorder callback fires every 100ms instead of 5ms as it should work and the following error is generated:

- Device : Nexus 5 Android 5.0.1
- Native buffer size 240 samples
(shorts)
- Native frequency rate 48000 Hz Player preset :
SL_ANDROID_STREAM_VOICE
- Recorder Preset : SL_ANDROID_RECORDING_PRESET_VOICE_COMMUNICATION
- AudioManager on MODE_IN_COMMUNICATION
It's important to note that if the audio route stays on headset it works fine.
Is any one knows what the problem?
