No sound from headphone Realtek audio in windows 8.1

I have a Toshiba sattelite p745-s4217 laptop, with 6GB Ram and 500 GB disk space. I upgraded my windows 7 to windows 8.1, 
my problem is I can not get any sound from my headphones, or external speakers, the sound just stopped working after I installed some updates .
I did install the latest Realtek audio driver for windows 8 64bit on Toshiba's website, but it didnt do anything.
I did try uninstalling the realtek device in device manager, it does NOT help.
I could make it work only once by going to safe mode and installing the realtek driver, there but after a couple of restarting the problem came back and again I have no sound in my headphone.I tried to go to safemode again and unistall the dumb realtek driver and installing it again , but this time didnt get any sound back like last time.
I have tried many things, for example installing the realtek driver in windows 7 Compatibility mode, or installing it as administrator.
nothing helps. it is extremely frustrating, I wish I had never upgraded to windows 8, I don't know what else to do,
please do not offend me by telling me to check the Volume in playback devices, because I have tried all of those things in the Microsfot community, it seems like nobody knows here how to fix this problem, I have full sound in ubuntu without any problem in both laptop speaker and headphone.
I have other problems btw too (but I dont care about them right now so I dont seek help for them here), here are list of other problems windows 8.1 gave to my laptop.
1-since I upgraded to windows 8.1, my wifi drops every 5 minute, so I have to use ethernet cable 
2- my laptop over heats every 20 minutes and restarts, while I have nothing opened but netflix. really frustrating.

Did you follow  these instructions to upgrade to Windows 8.1?

If not, try installing all updates available from Toshiba Service Station and Windows Update, uninstalling all items from Appendix A (which includes any Realtek audio drivers), and then installing all available updates from Toshiba Service Station and Windows Update once more.

with all due respect, I think the problem is the toshiba dirvers, anytime I fix the probolem, and then try to install the toshiba's anything on the site, the whole systems fails on many things, sound, over heat,wifi...keyboard , usb
