Hello there. I figuried this out. Sound doubles through my Stream Deck sound source ONLY when i launch OBS through it by Launch button. When i start both OBS and Stream Deck software separatly i dont have this problem. Happy New Year!Hello! Thnx for answer. Im kinda new to OBS. Yeah i tried that but then i dont hear the alert and when im in the middle of an action i could miss the alert and dont respond in time. I also tried to use "Control audio via OBS" with monitor on but result the same -streamdeck audio capture my deafult (or assigned) audio device a and doubles playback. I use streamdeck like soundboard. Interface of stream deck doesn't have auido output settings (or i just cant find it). Im gona try voicemeeter virtual cable. Mb that will help somehow idk.
