Newbie question 1 - Start scene with only Image and Media sources but records my microphone audio input ... Normal ? Best practices ?

[Lionel_M]

Hello there OBS Forum !
Today is my first OBS day and I have lots to learn and discover, so there will be lots of questions are here's the first one :

- I have a "Start" scene with only "Image" and "Media" as sources; but it also records my microphone audio input.
--> Is this normal ?
--> Is there a way to avoid ANY audio input other than the Media I am playing ?
--> Is there any best practices here ... I guess rather than using the AudioMixer and muting the audio sources

Basically I want a video start sequence with only an image and the mp3 I have selected ...

Log file attached here, as I couldn't Upload the last log file (I guess this will be my second Forum question if I cannot find an answer on the Forum :)).

Thanks a bunch in advance for your help !

way passed time to update OS
make sure your Symantec is patched (not just LiveUpdate) and settings configured to not interfere with streaming (don't assume defaults are ok)
Ultra-low power laptop CPU - make sure you actually need 60fps. I'd recommend 30fps until to learn more
and a lower FPS should help avoid
11:34:58.140: Output 'simple_file_output': Number of lagged frames due to rendering lag/stalls: 2404 (15.0%)


as for audio, per you log
11:16:16.296: WASAPI: Device 'Speakers / Headphones (Realtek Audio)' [48000 Hz] initialized
11:16:16.296: [Loaded global audio device]: 'Desktop Audio'
11:16:16.453: WASAPI: Device 'Desktop Microphone (3- Microsoft® LifeCam HD-3000)' [44100 Hz] initialized
11:16:16.453: [Loaded global audio device]: 'Mic/Aux'
11:16:16.456: [duplicator-monitor-capture: 'Display Capture'] update settings:
11:16:16.456: display: 2 (1920x1080)
11:16:16.456: cursor: true
11:16:16.587: WASAPI: Device 'Speakers / Headphones (Realtek Audio)' [48000 Hz] initialized
11:16:16.594: WASAPI: Device 'Desktop Microphone (3- Microsoft® LifeCam HD-3000)' [44100 Hz] initialized
11:16:16.594: Switched to scene 'Scene'

So, you have multiple audio sources, not none
- make sure your audio sampling rates are the same (don't mix and match 44.1 &48 KHz)
and
11:16:16.599: - scene 'Scene':
11:16:16.609: - source: 'Audio Input Capture' (wasapi_input_capture)
11:16:16.609: - source: 'Audio Output Capture' (wasapi_output_capture)
11:16:16.609: - source: 'Video Capture Device' (dshow_input)
11:16:16.609: - source: 'Display Capture' (monitor_capture)

Personally, I found (as I didn't need it), that Disabling all of teh Default OBS Audio sources helped avoid loops/echos, then added specific audio source per scene as needed. There are reason to NOT do this, but might make it simpler for you to get started and learn OBS Audio.
maybe watch

Your webcam is an audio source, so be careful
