Ok so I'm doing a new install on mid 2015 MacBook Pro Retina my, wife's new machine. The realtec audio driver hung up. it seemed to stop working, but curiously i was able to freely work around windows. I had no sound but had full access to windows. I found the post from lincizy and jmwils1, see posted below.

I found a solution, when the installation hangs at realtek audio:
1. DO NOT turn it off
2. go to your bootcamp folder, manually install the realtek driver, DO NOT restart
3. after manully setup, open Task Manage, and kill the "RealtekSetup" process
4. bootcamp will skip the Realte, and have fun

I am so thankful I found this. I am having the same issue on a new 13" 2015 MBP retina. Bootcamp installs Windows 10 fine but the setup hangs at the Realtek step. I tried installing manually without luck and couldn't get the trackpad to word so I could right click on anything. After 20 minutes on the phone with Apple Support I was told it was a Windows issue with the drivers they supplied and they can't help me. They suggested that I contact Microsoft. I did and they couldn't help since it was an Apple product.
I wanted to clarify that in the above solution, click control+option+delete to get to task manager. It will show "Setup" as the running process. Do not end this task. Instead click on "More Details" at the bottom and scroll down to find "Realtek Setup". The instructions by lincizy were exactly correct, but you have to expand the "More Details" to find it. I am now running Windows 10 and have a working trackpad.
Thank you so much lincizy!
I found in my case that after waiting a few minutes (5 ish) I began to follow linczy's recommendation. Sadly I was surprised to find that the windows support driver's and ISO never made it to my USB drive. The drive was blank. I am running BC 6.0.1 (522). I had not seen this before. I have a MID 2013 MacBook Pro running Windows 7 Pro (Absolutely Love it, BTW) and the USB drive had the support drivers and ISO files onboard. As I began to panic I wondered, so I followed jmwils1's suggestion and simply bypassed, or so I thought, the realtec driver install. the drivers continued on and boot camp completed without further issue. When I tested the system sound I found that it was working correctly. If I was a betting man I would bet that the hang comes after installation of the realtec driver and just never moves on.
It is curious that after weeks of prep and review I found no such mention about the lack of need for the USB drive for this install. I had never seen a cross partition installation before. I followed Create an ISO image for Boot Camp from Windows installation media - Apple Support this article only to find that the image below never appeared. I guess the new BC assumes this and skips it. The only reference I find is the ability to DL the drivers to the USB from the menu above. I say all this because following instruction is easy, but when the instruction is at odds with the software it tends to freak me out.
Hope this helps any future patron's. Please excuse the post length but i felt more context was appropriate.
