OBS Projector Audio Missing in Discord

If friends can see your OBS projector window and hear nothing, the preview is doing what OBS designed. Projector mode is a picture. The mix is elsewhere.

OBS forum threads on silent projector mode say the same thing I am repeating: the projector window, including fullscreen projector of a source or of the preview, is a monitor for video. It is not a second copy of the audio bus. Discord's screenshare then captures that window's picture and, depending on the operating system, little or no sound from it. The game audio still exists in OBS if you added an audio source. It is just not glued to the projector window.

First confirm that the game’s audio appears in OBS’s Audio Mixer. For sharing the original game, Discord’s supported application/audio sharing is the simplest path. For sharing a composed OBS scene, the projector window supplies video while the mix needs a separate audio route. OBS’s Audio Mixer guide documents a monitoring device and per-source monitoring controls; route that monitored mix to the audio device Discord is actually sharing. Virtual audio routing may be needed for that composed-scene setup.

Monitoring labels vary by OBS version. Use the installed version’s monitor control rather than assuming every release has the older “Monitor and Output” menu. Avoid sending the same monitored signal back into an OBS capture source, which produces doubling or feedback. Discord audio capture also varies by operating system and share type; consult its current Go Live support page.

A projector in the living room is a red herring. The word projector in this query is OBS's projector, the floating preview, not the lamp in the ceiling. If you also display the game on a ceiling projector, that HDMI feed is independent of Discord. Fix the stream audio in OBS. Do not rewire the ceiling unit.
