OBS only recording Audio on Track 1

[Great Taz]

So I like to have a separate track for my Game Audio and Mic Audio when I do recordings. This way if I need to Edit out a sound on the Mic I don't affect the game sounds. This makes for better Video overall sound. I have run into an issue and am not sure how to fix it. I've searched and even investigated the Issue using the troubleshooting on OBX's site but nothing seam to fix the issue of no sound being recorded on any track other than 1. I record in .MKV format then Auto Remux into MP4. in both replays of the MKV or MP4, there is no sound when I change to any track other than 1. I have looked at the log file myself and well not 100% what it all means so here is the link.

Please someone HELP.

Are you in Basic mode? (Settings -> Output) Basic mode is Track 1 only.

In Advanced mode, you can choose which one Track to stream, and which Track(s) to record.

Well, that did not fix it. it however WAS set to simple for some reason. I did a test record and went through all the tracks 1 by 1 and only heard game or mic audio while track one and only track one was selected. I watched/Listened to the replays in both recorded formats (MKV and MP4) and there was no sound unless track 1 was clicked.

Nothing jumps out at me in the log.

You really get nothing when you send something to Track 2, record Track 2, and select Track 2 on playback? (those are three different things, BTW)

What happens if you record all Tracks and send something to all Tracks? Maybe have 7 unique sources (generate them in Audacity if you have to): 1 of them goes to all Tracks, and the remaining 6 go to one Track each so you can tell if the selection works.

No, I get nothing I wish I could attach the video I just recorded but even zipped it tells me it to large. Even a 30-second recording and the site says it's to big, even zipped and compressed.

This issue is Super New since I recorded this video (https://youtube.com/shorts/VaCm3F9s3DM){recorded around 5-7 April} and had no issues. I tried to record yesterday and today and I got the Issue.

Did you update something between then and now? Manually or automatically? If it used to work and now it doesn't, then something had to have changed.

Can you screenshot all of those settings, and anything else that might possibly have something to do with audio? I think it's more likely that you missed something than a bug. Maybe you (or someone else that has access) played with the settings and didn't put them back?

If the video is not moving at all - static image, solid color, or all-black; best would be to not have any video source at all - then the file should compress *really* well. It's when you have something non-trivial for it to preserve that it takes a ton of space.

But I don't think it's needed just yet. Let's see what the settings are first.

I don't think anything has been updated but I cannot say for sure 100%. SO screenshots of the OBS settings?
I will ASAP.

DO you want all the SEttings or just certain pages?

 

[AaronD]

DO you want all the SEttings or just certain pages?

Everything that has something to do with audio.

 

[Suslik V]

and the filter's page, especially "Noise Suppression" etc.

 

[Peter_JY]

Has Advanced Audio Properties been properly set? (maybe so-called in English)
Make sure you've seleced different origins to different tracks.

 

[Great Taz]

and the filter's page, especially "Noise Suppression" etc.

Not sure how Filters are going to matter.. since I'm not using any but here you go.

If there is anything you want else let me know... I'll check back soon.

That's the Desktop Audio filters. What about the Mic? You say "not using any", but just to be sure. :-)

Yep, you're recording Tracks 1, 2, and 3. So if something's being sent to them, it should be okay.

What do you have in here?:

One other note: you still have the Desktop source set to Default, which is kind of a wildcard. It won't cause this issue, but it could give you a surprise when Windows decides to connect "Default" to something different. That's kinda what "Default" is for: it gives the best possible chance of getting *something* to work immediately after install, precisely because it allows the OS to decide what that something is. But that something can also change without warning. Once you know what your devices are, you should set each one specifically and not use Default anymore, so they stay as you expect.

And, if the Desktop source is connected to the same device as the Monitor, you can get feedback or an echo, depending on the Monitoring settings in the same window above.

Log-file says that you are using 3 filters for the source named 'Mic/Aux':

...
15:51:38.145: [noise suppress: 'Noise Suppression'] NVAFX redist is not installed.
15:51:38.146: [Loaded global audio device]: 'Mic/Aux'
15:51:38.146:     - filter: 'Limiter' (limiter_filter)
15:51:38.146:     - filter: 'Noise Suppression' (noise_suppress_filter_v2)
15:51:38.146:     - filter: 'Gain' (gain_filter)
...

And where is screenshot of the main menu Edit > Advanced Audio Properties ?

Yes and that is due to the fact I currently have a Windows AC Unit within, like, 3 feet of my mic and am trying to cut out the background noise

 

[Great Taz]

I have not had an issue till I upgraded to Version 29.
I have downgraded to 28 and have not had the issue!
Just trying to keep it up to date as much as possible because of new features.

Mic I have "Limiter", Noise Suppression", & "Gain" to stop the Background noise of a Window AC and/or Fan from being picked up. This is for when I stream or record. I get Voice into Track & Desktop into Track 1 and not 2 or 3. I'm not sure how a Filter is stopping Tracks 2 & 3 from recording Audio.

Assuming you still have the combination of settings from those two posts, you should have multiple tracks in the MKV file. It's just a matter of getting something to use them. Do you have a player or editor that can select track 2 or 3? If not, then that's your problem. They only play one at a time, not together.

For the acoustic noise, a lot of streamers shut off the HVAC and fans, even in the middle of summer. They do their stream, and then turn it back on again. Some of them do get quite hot by the end, by their own admission.

Maybe you could pre-chill for an hour or two beforehand? Set it way low so it runs constantly - low enough that it probably won't actually get there, you just want it to run - then shut off entirely for the stream, then back to where it was afterwards?

Also, I'm not sure whether the order of filters is reversed or not in OBS's log - I've written software both ways myself for various reasons - but generally, you want the noise suppressor to be first in the processing chain, and everything else after that. Gain and EQ are okay to have before it, but not a compressor, limiter, gate, or any other dynamic thing. It's just easiest to have a rule that puts the noise suppressor first, period, and the safety-net limiter last. Intermediate compression, EQ, and whatever else can be in whatever order works for you, between those two bookends.
