Fixing Wifi & Heaphone output on an HP Elitebook 7xx G2 running Fedora 21

Thought I'd make this quick post as I had to do a lot of searching about to get things working and it may be of help to someone else.

After trying a couple of different distros with this laptop I found that Fedora 21 installed largely without issue, however the wifi wasn't working and also later found that the headphone jack wasn't producing sound. 

Fixing the wifi:

1. First update some packages 
• sudo yum update 
• sudo yum install kmod-wl broadcom-wl
2. Edit /etc/default/grub
• sudo vim /etc/default/grub
• Add intremap=off to the end of the line GRUB_CMDLINE_LINUX=
• Run grub2-mkconfig -o /boot/grub/grub.conf
3. Reboot

Fixing the headphone audio:

1. Create the file /etc/modprobe.d/snd-hda-intel.conf (sudo vim /etc/modprobe.d/snd-hda-intel.conf) and add the following
• alias char-major-116 snd
  
  alias snd-card-0 snd-hda-intel
  alias snd-card-1 snd-hda-intel
  
  options snd-hda-intel id=Generic_1 index=0
  options snd-hda-intel id=Generic index=1
  
  options snd-hda-intel model=hp,headset-mic
2. Reboot

Now if someone can just work out how to get fglrx working without issue everything would be set up!
