For those having problems with looping activated sound:
Make sure you have the proper DirectShow filters installed on your system. Installing the Combined Community Codec Pack is the easiest way to do this.
The next step is to use Clean Boot Mode which effectively shuts down all non-Microsoft startup programs and services at boot time (eliminating any 3rd party conflict possibilities). If this corrects the problem, you need to check your computer configuration for the problematic program.
If you still have problems, please run the command "sfc /scannow" from an administrator command prompt to ensure your system has its proper system files.
This solved my looping problem, Thanks.
Now i have to dig through my start-ups to see what it is.
I really appreciate it Neo7.
I found a way to replicate the unlimited sprint not working. It is only when you upgrade the second two lung upgrades to add extra time to your sprint. So just do not upgrade the added time to sprint and it works just fine.
Confirmed here.
