Make sure you set networking "Buffer thread priority" below general "Process priority", so the playback process has higher priority then buffering process.
For example: use
Above Normal priority for "Process priority" (playback)
and
Below Normal priority for "Buffer thread priority" (buffering)
to eliminate delay at the start of playback.
