1) First off, most delay(90%) is introduced by the limitation of trial version. See:
http://www.virtualaudiostreaming.net/faq.html2) Besides removing the noise in trial version, audio delay is also depended on your system performance and the VAS buffer size. So, if you have already registered VAS, you can farther remove the delay time by reducing VAS buffer size on the right panel of VirtualAudioStreaming.
To reduce the delay, try reducing the buffer size in the right panel of VAS(named 'output audio to real sound card'). Change the size to 512, 768, 1024, etc. to test. You may have to click 'stop' button before you can edit the buffer size.
3) You may also use Windows system internal audio streaming if you use Windows 7/8. You can try below configurations:
1) Set VirtualAudioStreaming(VAS) as your default playback device.
2) Make sure you unmute VAS:
3) Close VAS. Complete exit it from system tray.
4) See attached listen-to-virtualaudiostreaming.png. Let VAS play sounds to your physical speaker.

Now try again, there should be no delay now.
