Need help with audio setup on SM-P600 Galaxy Note Tab

So I have a galaxy tab running on android 4.4.2

I need to be able to have a microphone plugged in using 3.5mm but still output to my bluetooth speakers. Is there a way to do this without rooting the device?

This tablet will be used to make Skype calls on a factory floor, so there are not any native bluetooth microphones that I can use that will keep the sound pollution out.

I can connect the speaker using 3.5mm as well (I have the y-splitter) but the higher-ups really want the speaker to be running on bluetooth.

Samsung Galaxy Tab 2014 (smp-600) firmware update

Well, I have the tablet for well a year and a half, and have loved it.
I have kept it stock and accepted all firmware updates blindly as I never had an issue with them, until the one I got a few days ago.

Ever since this most recent update the tablet has been running extremely hot, and battery life went from acceptable (several hours a day) down to less then 1 hour of run time since this update.

Of course I didn't note what version I was running before the update, but I can tell you what I am running now:

Android 4.4.2
Kernel 3.4.39-1462259
Build KOT49H.P600UEUCOI1

What is very odd is that I don't see anyone posting anything about recent updates to their SMP-600??? was I slow to get an older update? I keep set to auto and is always connected.

I did see a post about a cracked battery connector, and while I cant dismiss this may be the problem, the fact is that the overheating and battery life issues started immediately after this update and not after a drop or any other physical abuse that I would associate with a cracked batter connector. This thing lives on my sofa and never leaves.

Anywho, just looking to get any thoughts out there about this update? At this point I suppose I would like to roll it back to what it was previously.
Thoughts? do I just root it now and try a different firmware? or do I have to root to roll it back?
