I changed the file cstrike.txt. Maybe that?
Otherwise I added customs sounds for start and end sounds. In a different folder , not in TF2 Folder.

And I changed a few lines in. Cfg.
Moreover, some songs are quite long (I'll shorten them), sometimes longer than the vote, right?

I don't understand. You suggest to remove MapChooserExtended to see if the problem persists?
