Fix audio output to play audio other than 44k stereo

When opening an output stream, the driver needs to return its
 format, sample rate and channel mask. Failure to do so will
 cause AudioFlinger to create the ouput as DIRECT, regardless of
 the output flags.
The consequence of the output thread being in DIRECT mode is
 that no mixing is done (one sound at a time), and only audio
 that plays at the HAL's expected audio characteristics (44k
 16bit stereo) can be played.
The fix consists in returning the format, chanel mask and sample
 rate values when opening the output stream.
