cl_filterstuffcmd disables music in single player

[OurMajesty]

When cl_filterstuffcmd is set to 1 in config file, no music (soundtrack) is played whatsoever.
There's an error in console about trying to exec cd command:
could not execute privileged command ...

So, to have full experience and also be somewhat secure, you have to change cvar manually each time you go mp.
Shouldn't be there some checks, that commands are executing from single player game server?
