Disable sound on pc.

[bemyfrnd]

I am sorry if this is a stupid question, but I cannot find how to disable audio on pc. I am using phone as mic (Mumbla client) but I just want to transfer my audio to the game, not to myself (hear myself from pc)> Thank you! Edit: i am using pipewire Edit 2: Also forgot to mention, I tried muting my phone through desktop client, but then the audio doesn't passes to recording software. I am on arch linux.
