Root CM7 - Call audio through headphone jack possible?

[uguu]

I just recently decided to make the jump to CM7 and its my first time using CM7 on any device. I hook up my phone to my car through the headphone jack and use the aux in, and the stock rom would put call audio through the headphone jack but CM7 doesnt. Is there a setting I'm not finding or an app needed or does CM7 not do this at all?

EDIT: I formatted data/cache/system prior to flashing CM7

Mine does that just fine. I don't think I made any changes to make it happen, but I can double check and report back.
