I pushed too many buttons
Howdee have come back to Ntrak after quite a few years. n re learning the program, I seemed 
to have stopped any volume coming out. All tracks are registering but I cannot hear it, any any ideas anyone cheers
Re-install n-Track.
Check in the settings menu under audio and see if perhaps the audio out is not set to the correct setting. Make sure you have not muted the track. If nTrack is showing that the sound is being produced (look at the playback vu meter, if it shows activity, the problem almost has to be with the audio settings, or interface.
