I am writing a voice application for HTC-G2 (MyTouch) phone. I am
using Audiotrack class (along with Audio Manager) to play audio in PCM
format. It works fine but audio comes out from speaker phone instead
of earpiece. When I use IsSpeakerPhoneOn() to query the status of
speaker, it comes out to be "off" (false).

I even tried SetSpeakerPhoneOn(true) and then SetSpeakerPhoneOn(false)
to make sure that I explicitly set the speaker to off but audio still
comes out of speaker. Interestingly, I checked IsSpeakerPhoneOn()
after setting SetSpeakerPhoneOn(true) and that API returned False.

I tried setRouting API to set ROUTE_EARPIECE but that API seems to be
deprecated.

Can someone please tell how to route audio to earpiece? I was under
the impression that earpiece shall be the default route for audio but
it does not look that way.

Thanks,
