Yes, no error messages [thanks]. You had told me in the other thread:
Neither of the programs that you listed seem to have support for plug-ins (I checked by searching for the word 'plug' in the features page, so I might have missed it).
That means that you'll have to use a program that sends the audio to Stereo Tool instead of to the sound card. But that will cause latency.
Since my purpose is only for music playback and no mic involved I am guessing no latency issues involved here but can you recommend any "program" I can try out to use with any of my playback softwares and ST?
