This patch ensures that the audio_output_win_unittest works for AUDIO_PCM_LOW_LATENCY.
It seems like only test which utilized AUDIO_PCM_LOW_LATENCY has been broken for a while.
It was most likely I who broke it when I added support for WASAPI output.
Anyhow, in this patch, I ensure that we can still test using the low-larency flag.
A buffer size of 10ms is used on Vista and higher (<=> WASAPI) and 50ms is used (as before)
in XP.
I have also modified the sinus source since it contained two issues actually.
1) It did not store a valid state between each frame (=> distorsion at end-points).
2) The volume 2^15 was too high and could lead to odd effects for negative numbers.
Both these things are fixed in this CL and all tones now sounds better. The old tones
were all distorted.
BUG=none
TEST=audio_output_win_unittest
