For people's consideration. Restore the .11 behaviour of not initialising sound if music is turned off. Reason. I still get 100% CPU useage in frontend due to sucky sound daemon setups *cough*pulseaudio*cough* so this offers an easy workaround for people (turn off music). Disadvantage, this removes Smaxx' code to disable sound-related buttons on failure to init sound.
