[Qemu-devel] [PATCH]] audio: previous audio buffer should be flushed

[munkyu.im]

Winwave audio backend has problem with pausing and restart audio out.
Unlike other backends, Winwave pausing API does not flush audio buffer.
As a result, the previous audio data are playedin front of
user expected sound when user restart audio.
So changes it to waveOutReset()
