1080p60: Set OBS’s output resolution to 1920×1080 and its frame rate to 60. RelayCast won’t upscale a smaller output.
Audio: Unmute your sources and enable track 1 in Advanced Audio Properties. Kick needs stereo at 48 kHz or lower. Every destination gets the same picture and audio.
Stop: Use Stop all in RelayCast. Closing its panel keeps streams running; OBS’s normal streaming button is separate.
