comment?  for example how does this differ from MakeAudioOutputStream()?  In
fact this method definition should be moved underneath MakeAudioOutput() to make
the distinction more clear

const AudioParameters& params? (you seem to use const refs in other parts of
this patch and I think you said you were going to switch over in a future CL)

Done.
Changed it to const ref for this method. Will update MakeAudioOutputStream() in
a separate CL.
