Question / Help how to turn off OBS sound while recording?

[joejim]

I have PC, Win 10, (2) monitors. Trying to record LIVE stream sports game with OBS.
I picked Browser input, entered Firefox web link(not URL), now OBS has sound from web link. Also I got sound from Firefox,
So I got two sounds playing on my PC.
The question is how can I silence OBS sound (but still record sound in OBS) while recording?
This way I can still watch and listen Firefox while recording OBS.

In OBS, open the properties for the browser source and select "Control audio via OBS". This'll route it to the live stream, but not to your speakers (by default).

Any advice for silencing sounds captured specific windows?
