Your 14e4:4365 device works with the Broadcom STA driver in Ubuntu 13.10. Please get a temporary wired ethernet connection and open a terminal and do:
sudo apt-get install bcmwl-kernel-source
sudo modprobe wl
Do you now have a wireless interface, ideally eth1?
iwconfig
Does it scan and see networks?
sudo iwlist eth1 scan
If there are errors, post them here.
If you previously attempted the compat-wireless package, you will need to uninstall it so as to resolve a probable conflict:
cd ~/Desktop/compat-wireless-whichever
Or compat-drivers or whichever you attempted to install.
sudo make uninstall
Reboot. Please get a temporary wired ethernet connection and open a terminal and do:
sudo apt-get install linux-headers-generic
sudo apt-get install --reinstall bcmwl-kernel-source
sudo modprobe wl
I found the solution to your problem!
Install alsa-tools-gui (sudo apt-get install alsa-tools-gui)
Start hdajackretask (either enter that in the terminal or find it in Unity)
Select the codec: Realtek ALC668
Check Options -> Show unconnected pins
find Pin ID: 0x1a
check Override and select Internal speaker (LFE)
press Apply now
If it works fine, select Install boot override and reboot.
Have fun with your subwoofer!

This is what worked for me:
first, install and run HDA Analyzer:
wget -O run.py http://www.alsa-project.org/hda-analyzer.pysudo python run.py(root is required)second, using the gui do this:
•PIN 0x17 -> Widget Control -> Check OUT and Uncheck Mute:
•PIN 0x1a -> VREF -> Set it to 100:
And third, test it by listening to some music.
If it still isn't working, you can follow this thread, maybe someone will find an answer:
