Youtube and iTunes sound problem.

Install this software from Microsoft to rectify that problem:-

Download: Microsoft Visual C++ 2010 SP1 Redistributable Package (x64) - Microsoft Download Center - Confirmation

Did you manage to solve the missing mfc100u.dll problem?

I just found out that the drivers come with a Realtek HD audio manager for your sound card.

Perhaps there are some relevant audio settings there that you can manipulate to fix the remaining minor issues?

no not yet. i am trying to run a program and there's still a problem related to mfc100u.dll.

the trouble that i am saying is like when a speaker is grounded.

It could just be related to the fact that we did a Clean Boot on your system; you could always just tick all the boxes we unticked earlier to see whether your mfc100u.dll problem goes away.

Which program are you trying to run, by the way?

Yes, all the rep is welcome! Please tick the thread as solved on your way out!
