No, not really. You mean built in spotter/engineer, not CrewChief, right?
Have you checked your headphone or speakers for surround spatialization? Sometimes some frequencies get eaten by that. I had that with my new headset until I noticed, that for proper surround simulation I had to install DTS-X. After that sound was crystal clear even in virtual surround mode.
But the engineer could give a few more helpful advices. I hope KUNOS implements more variation, more info through the engineer. I believe the did so in past upgrades as well.
Lately I almost do not miss CrewChief, when it is not running...
