CC Audition 2018 (11) Input Monitoring Issue

Hi there,

So I recently upgraded to Audition 2018, and I'm having a slight issue with the Input Monitoring on Multitrack.

Specifically I can hear the input through my output (headphones) irrespective of whether I press the 'I' Input button next to the 'R' Record button, or not.  It's also got quite a large delay on it now, which is annoying, but as I generally monitor through my pre-amp, rather than through Audition, that's not a huge issue for the time being.

However, it there a way to ensure that it only monitors the Input when the 'I' button is activated, rather than all the time?  Is anyone else having this issue?

Thanks!

Ed
