I have a project that I have been producing on Sonar 7 and suddenly the latest version of the project wont play. The transport bar moves, but there is no audio heard or visual. It is almost as if an in visible track has been solo'd is probably the best way to describe it. The project has Ableton as a rewire device and there too, zero audio both visual and hearing, ie no movement on the audio meters.
 
If I load any previously saved versions of the track, they all play perfectly. Any ideas?
 
Is there a way of copying 'system parameters' from one of the previously saved versions of the project over to the latest version that is not playing?
 
Thanks

Sounds like a routing issue, or a bus plugin whose output has been turned down. Do you hear sound if you route any of the tracks directly to the hardware rather than through the master bus? Also, look at the toolbar at the bottom of the screen and make sure there is no "S" or "M" icon lit that might indeed indicate a soloed track or bus.

Thanks Bitflipper,
 
I will try rerouting directly to the hardware first, I appreciate that you took the time to give me a pointer.
