Is There Any Way to Disable My Mt4 Sound?

Hi Guy's i need to know is there anyway to Disable my Mt4 Connection & Disconnection Sound also i am using moving average crossing indicator means whenever they crossed each than alram produced i also want to Disable that alram sound but seems iam failed to Disable all the distrubing sound's.
I go to !
Tool ---Option----event's but after disabling all nothing still happened in my favour. I was woundering is there any way to mute/disable all sound's???
Thank's In Advance

tools, options, events and then uncheck the box near top that says enable.

Thank's Magnum But Still i can hear the indicator crossing sound. I am able to get rid of conncetion & diconnection sound By tool's , Option , Event & Also by Unchecking the box.
Thank's Again

they must be calling the function playsound from the indicator. Do you have the mq4 file for it??

Ahh I think i got the way how to get rid of it...Thank's Magnum you seems to me one Heck of a guy around here.

If you don't ever want to use sound, you could always delete the files in the "sounds" folder. I do that with my server setup. (10 Metatrader isntances going off ain't fun)
