This latency is a fixed value, not a real latency for audio data path.
In fact, it's a total buffer size.

I guess the bufferCount is the sizeof integer which is 4.
The second term is something audioFlinger and audioTrack is
introducing. Needs to be figured out.
The latency introduced is not acceptable for real time applications.

I have this same question regarding the buffering. What I can say is
that I think the reason that the second term is bigger than the first
is because the mFrameCount can be 4 times the size of the driver's
output buffer (or a little bit more). mFrameCount is calculated in
MediaPlayerSer
