Soud lost on Wavelab6

Following a lot of tampering aimed at successfully capturing a video of my screen with sound, I lost the sound on wavelab. Audio files that were previously no problem are played without audio. The meters move, but the sound does not come out. So I uninstalled the video capture software that I thought responsible, without success. Finale works normally, Cubase too, but no sound on wavelab. Now I use it a lot. Does somebody have an idea ?
P.S. My operating system is windows vista (I know … but as long as it worked …)

you can’t imagine the worst set of circumstances, I would put Windows 8 or 10, then the program for capturing the old version and try to restore :slight_smile: :slight_smile: :unamused:
