OBS recognized the audio from my capture card but I cant hear it (viewers from stream can hear the sound)

[gwapogi5]

Hi sorry if what I am asking maybe basic.

Basically I bought an unbranded Capture card with good reviews.

the video and audio are working properly and OBS can detect it. However I do not know how to configure OBS such that I can hear the sound from the capture card. my capture card has no audio output of its own just a simple HDMI to USB

Setup:
Ryzen 5 3600x
16gb ram
RTX 2070 super
Unbranded HDMI capture card
Nintendo switch

I cant connect my audio directly to the switch because it will remove the sound from the HDMI output

If the capture card audio goes out to the stream, the capture card is working properly.
As default, OBS is just doing this: it sends the capture card audio to the OBS output - stream or recording. It doesn't output the audio to any Windows audio device.

There are 2 ways of getting its audio to the audio devices of your PC for monitoring purposes:

• in OBS, in the properties of the capture card source, scroll down to the bottom. You find the "Audio Output mode" option. It's set to "Capture audio only", which means the audio is just being sent to the stream. If you change it to one of the "output desktop audio" options, OBS will instead output it to the default desktop audio mic device. You can also enter a specific device, if you activate "Use custom audio device"
• the seconds way is in OBS->Edit->Advanced audio properties. Locate your capture card source in that list and change the "Audio Monitoring" setting from "Monitor off" to "Monitor and Output". "Monitor off" means OBS is outputting that audio to the stream only (your current situation), and "Monitor and output" will additionally output audio to the monitoring device. The monitoring device can be configured in Settings->Audio->Advanced->Monitoring device.

There is a small but important difference between both ways: the first will output audio to some recording device (mic), the second to some playback device (speakers/headphones). Choose accordingly. Make sure to not output to some device you're also capturing with OBS, or you will create an echo or a hollow sound.

Playing with OBS and trying to get my sound going to zoom from OBS.. I have a question If its on Monitor loopback and my airpod gets the sound but it I put it on Monitor off (I get nothing in loopback or the airpod's) so if I put in on Monitor and Ouput I get everything. so it looks like the output Is going NO WHERE!!
Can someone please help me understand on where output goes!

I'm trying to use OBS to do some basic greenscreen stuff with my kids, since I'm using Linux there seems to be no better chromakey software. I have a recorded video from my DSLR camera and using the chromakey filter, I can remove the background. And when playing the video in the editor, I can see the "Media Source" audio bars jumping around, but I can't hear the audio from the movie. I've been googling around for an hour now but all the "OBS no audio fix" tips relate to either Windows or sound not being recorded. How can I listen to mediafile audio when in the editor? The above info from @koala does not work for me because there is no source configuration for a media file anywhere in the 2 locations he described above. Also this posting (https://askubuntu.com/questions/1321546/no-desktop-audio-in-obs-studio) did not help, my mixer does not have anything muted.

You're asking about Linux, now, in an old Windows thread? Might be better to start a new thread in the appropriate section to what you're actually doing.

Regardless though, have you checked the Advanced Audio Properties?:

Specifically the Audio Monitoring section.

• Monitor goes to a hardware device that you select in Settings -> Audio.
• Output goes to the Tracks selection here.
  • Simple mode (Settings -> Output) only uses Track 1 to both stream and record.
  • Advanced mode can choose any one Track to stream, and can record any or all Tracks as "alternative audio". They stay separate - no mixing except to assign things to the same Track - and a playback app/device can select any one Track at a time.

Activating "Monitor and output" will make the media audio also going out to your speakers as AaronD wrote. However, make sure you don't record the speakers at the same time. If you do record the speakers as well, you get the media audio twice on the recording: once directly from the media source and the second time indirectly from monitoring via speakers. This will create some kind of hollow sound or echo. This will go away by seting the monitoring option to "monitor only", so the media source audio gets to the speakers, then recorded from the speakers, and not directly to the output.
