No you cannot disable liquidsoap .It is the core-engine.Its actual what gives the audio.
Airtime consist of the web ui and the audio-engine(liquidsoap).
Try Using any other device to monitor,like an additional machine(laptop or desktop) ,barix or I used a raspberri pi ( my type of barix).
I have a 2496 audio board,I do not use the audio out, only the audio in for my mixer and for live studio
Good Luck VOISSES
Anyone reading this a find it funny about my grammar , I make no apology ,Go get a translator. "The Problem with education today is that it takes a university degree to switch on a light bulb" "You learn from your mistakes but wise people learn from others mistakes avoid Making mistakes there is not sufficient rooms to make them" "Innuendo","If's","Assumptions" and "Fear" are for politician.Who,What,where,When and How are for those seeking knowledge and care about Humanity. "I might be in Mud but that does not Make me a Wild Hog(pig)" “Any intelligent fool can make things bigger, more complex, and more violent. It takes a touch of genius — and a lot of courage to move in the opposite direction.” "The only thing that remains constant is change itself" May the force be with you,until our path or destiny bring us in tandem.
