Remove Audio from Recording

[The Killer Ref]

Hi, I am doing multicast streaming through OBS by using the Live and record feature and its a great result however, I want to mute the sound on the recording option but even when i disable encoder, the sound is still pumping out
What am i doing wrong??

So I have managed to fix this myself
I enabled the Audio output to be set to a particular channel and then changed the recording stream to be looking for a different channel
this fixed the issue
