[Ardour-Dev] Lost connections!

[Er]

Hi! 

Lately I opened a song I used to open several time a day for weeks and *surprise* : no sound!

However if, in the mixer I change "output" into "out 1+2" or if I edit the connection I got the sound.... but my mix is ruined (very high output level).

It's not the first time it's happened, is their a way to reset default connection? Is there a reason that it happened??

Thanks!

Etienne
