Need advice on building a karaoke system with VLC activeX

[jacky912]

Dear all,

I am building a karaoke system for my home and successfully play the video file and change the audio track or channel after the file played.
However, I tested the following 2 methods to pre-set the audio track or channel before the video displayed. None of them success, please kindly advice:
1st method: set option on the playist add method: vlc.playlist.add(mrl,name,options). It works for audio track but not channel
2nd method: Disable the video (vlc.CtlVisible = False) and set the audio to mute, then pause the video. Setup the track or channel and enable the video again. Unfortunately, the video still shown when I set the .CtlVisible = False

Is there anyway to overcome the above problem? Your valuable comment is highly appreciated.

Thanks you very much.
