Audio gap

Hello,

I made a simple project: WAV player,
it uses waveOutxxx to play buffered raw sound stream.

When buffer was played, callback function immediately calls
waveOutWrite with next portion of data (already prepared in memory),
and after post a message, request for previous buffer
should be filled with next data from disk.

Everything works fine, but therez a short audio gap,
during disk operation of buffer is changing.

As I heard it was well known problem previously,
Please tell me how it could be fixed.


Thank you,
Ruostam.
