Dell :: S-XPS 16 Bluetooth / Sound Not Working

I love my new laptop but it has a few issues that i need some help fixing:

1) Bluetooth not working (Yes there IS a module in my computer): I went into my bios and checked to make sure the option for bluetooth was checked. When my computer boots, the bluetooth LED comes on but as soon as it exits the BIOS and boots Windows 7 the LED turns off. I've looked for new drivers, and looked around other forums for a solution for this but have found no direct answer.
EDIT: Solved. Download the driver here

2) Sound (I have The High Def Audio with SRS premium sound. IDT drivers)- When playing sound on my computer with the A01 bios version, and having the IDT audio drivers, I noticed a lot of weird things going on with the sound. It like bottomed out and had a lot of vibration or something. I dont know how to describe it but it was VERY distorted. Since then i've upgraded my BIOS to A05 and uninstalled my IDT audio drivers and let windows install its own high definition audio drivers. It seem a lot better but there is still some distortion there were it seems like the computer is just vibrating too much or something.. Is there a fix for this? I read in another thread that he had to take out the keyboard and adjust some of the screws that were messing with the speakers.

*Also when I plug in my headphones, i notice some scratching and weird sounds when im not playing any music. Its like I can hear the hardrive. However, the problem is inconsistent. Is there a way to fix this?

*Also are there some recommended settings for the SRS premium sound (if i solve this and get the sound working right)?

EDIT: Visit this thread to upgrade your BIOS to A05. It fixed this problem to me, and besides, its the latest BIOS version. It's currently not on the dell site (typical dell)
Also Uninstall the IDT SRS Premium audio software an go to the Dell site and download just the IDT Driver. It fixed the clarity problem i was having too.

3) Wireless card- This must have been a A01 BIOS issue but since I upgraded to A05, it has been fixed. Basically when running uTorrent, the card would completely crash. It would make Firefox crash, and any other internet required app

Also it would be EXTREMELY helpful if someone would create a thread with all of the latest S-XPS 16 drivers (1640 and 1645). That way much time spent searching and troubleshooting can be avoided if we can just have a thread with all the drivers displayed in one location. Dell is horrendous when it comes to the latest drivers

Oh and here is my system build:
