Is there a way to turn off sound in mame netplay?

I tried to disable sound in the options, and if I play offline it works but as soon as I play online the sound comes back. This is very annoying for me because I prefer listening to mp3s while playing. Any ideas ?

i dont think there is a option but you can do what i do

when the game starts press the ’ ` ’ key (above tab key)
and press the left arrow and make the volume slider go all the way down

no sound.

Nice trick, thanks !

YAY!! I was wondering this my self. Thanks, dudes!
