windows update or Flash Player causing issue with RealTek

[nickfree]

After updating my pc i started having a well known issue with realtek hd audio and my sound;
i had a popup baloon appearing saying 'you just unplugged a device from the audio jack' and then no sound.
and then somtimes reapering saying the oposite and got sound again.

i found some temporary fixes like going to device manager and disabling then reenabling Realtek, or running the inbuilt windows troubleshooter for audio and sound, but after a reboot same issue came back.
i tried to uninstall the drivers then reeinstal them but it didnt help.

so i restored the pc to before the update wich was like 4 days ago, and now everything seems to be fine.

in this windows update there was an update of Flash player for IE ,and i somehow suspect that this is the culprit.

might also be the update i manualy made for Firefox since i saw there was a new flash player version.

the reason i suspect it is the flash player faults is that when i had no sound, when trying to watch a video on youtube i got "an error occured", which wouldn't happen while i had sound, but i didnt really looked into this issue enough to verify it.

anyhow the problem now is that i would like to get those windows"important security updates"without them messing my pc.
and what to do with future updates?, i thought of hidding these ones so i know wich are the new ones.

Thanks.

these are the updates:

Do you have all the Windows 8.1 and 8.1.1 updates? There were some isolated sound issues after the 8.1 update and the current updates assume 8.1 has been installed.

If you go to the Desktop and then start Internet Explorer, Click on Tools then Windows Update. You can then select which updates you want to install (uncheck the Flash Player update for example). You can select all the ones you want or only select one at a time, install that (or them) and then see if sound is still working.

i should have mentionned it, i still use windows 8; i tried to upgrade to windows 8.1 the moment it came out, but it realy messed up my pc and i had to reinstall windows.

i thought of trying to install the new version of flash player just on firefox and see what happens [since the issue i mentionned about the error on youtube occured in firefox, (i havent checked it on IE)] ,
and if everything is ok then start installing windows updates one by one after creating a restore point first,
but i wanted to post my problem here first to see if there was a known issue before having to go through all the process of testing since im really glad now with everything working fine and dont want to risk pc's stability again.

It is coming from the update # KB2972280 if you uninstall this update, problem solved. I've gone through the same steps as you, I even went so far as to contact Microsoft 5 times and remote connect, no one has found a solution. Uninstalling this update will solve your problem though...
