Recording too slow via spdif

I am making recordings from mindisc or DAT using the spdif cable into a LogiLink 7.1 channel soundbox UA0099.

However, the final file is recorded too slow so that it sounds faster and a couple of semitones higher.

Whatever I do, I can't correct this.

What am I doing wrong or what changes do I need to make to Audition?

Thanks in anticipation.
