will this lead to problems in the audio signal?
Twisted pair ethernet is a balanced signal so should radiate little. If
your audio system is balanced too that will help.
With three shields between the audio and the ethernet twisted pair I
doubt if you'll experience problems. You don't mention whether the audio
cable will be carrying microphone signals or only line level - that
makes a big difference!
If you're really paranoid you could use star-quad audio cable. That has
four cores instead of two and much better inference rejection than
twisted pair.
