No more sound

[coolmatt]

Hi,

I came back to my on-going project but could not hear any sound. Levels of each track show that it is playing. Tried several times to reset output audio devices but no change... and if I load another project, no sound problem !!!
Did I press a key combination that disables all sound output on this project ???
Thank you for your help.

I would check to see if the master bus became muted, or there's a plugin dropped in there by mistake that's blocking output.

Also, do you have output for tracks set to default, or to specific output devices?
Are you using ASIO, and the desired output device is properly enabled?

Maybe try to narrow down where something is going wrong by using the various level meters. And please keep in mind that we are not able to look over your shoulder so the better your description of what's happening, the more likely you are to get useful help.
