I want to mute “music” bus:

FMOD::Studio::Bus\* bus = NULL;  
m\_pStudioSystem-\>getBus(“bus:/music”, &bus);  
bus-\>setMute(true);

But the music is still playing. I called “m\_pStudioSystem-\>update()” every time frame, and call “bus-\>getMute()” returned “true”.  
However, mute main bus is success:

FMOD::Studio::Bus\* bus = NULL;  
m\_pStudioSystem-\>getBus(“bus:/”, &bus);  
bus-\>setMute(true);

The platform is PC Windows.  
Can anybody help me? Thanks very much!

First thing to check would be the `FMOD_RESULT` that all FMOD functions return, if it is failing this will tell you why.
