Hello! Welcome to the forums here at Adobe!
As long as you can hear the sound when you play through your final sequence, you should have no troubles on export as long as your audio options are set correctly in your export panel. Nesting sequences as you've described is a very common task, and won't affect your audio at all.
Double check that your "Export Audio" checkbox is ticked in your export window. If it is not, then that would explain your problems. If it is checked, then there may be something deeper as the cause, in which case it would be helpful if you could post us screenshots of your audio mixer and the head section of your audio tracks in the timeline panel.
Also make sure that you're using Adobe PrPro 5.5 and that you have all the correct updates, including the RED importer, as new RED files don't work in older versions of Premiere. If the files were shot on the RED Epic, sound won't work at all in Premiere natively from the file (known bug) and so you'd have to use RED's Cine-X program to export audio files to bring in separately and sync to your video. However, you'd never get audio in your timeline at all, and so I think you would have noticed that issue before you got to export, so I'm guessing that's not your problem.
Good luck, and report back what you find with your export settings!
Hello and thank you very much for your help!
At the moment I use a Adobe Premiere cs 5.5 Trail. The thing is that when I export single sequenzes the sound works fine…the problem appears when I try to export the sequenz where I have copied all the single scenes together to make a rough cut. I made some screenshots!
Ah, I can't speak to that particular limitation of the trial version, but it wouldn't at all surprise me if it was indeed a limitation of the Trial... Everything looks correct in your screenshots, and as long as you can hear the audio on playback, you should also hear it on export, unless the trial limits it.
Ok thank you very much for your help!
Have a nice day!
