Audio recording broken with update?

Hi,

Violated the "if it ain't broke, don't fix it" rule and made the mistake of letting OBS update (now on 27.2.4). Now, of course, something that has worked for quite some time is no longer working.... Perhaps someone can direct me?

My use case is about as simple as it gets. I want to record a program that streams on the internet, but I want to have the local machine's speakers muted while doing it. I don't necessarily need to hear the audio of the school board meeting go on for hours while it records...

I've been doing this with OBS for years, it's always been very simple. As an example, recording a school board meeting. Open Chrome, go to their Youtube channel, find the video I want, start it and pause. Open OBS, choose that window to record. I make sure everything's working (I see the meters moving in the Desktop Audio) and then I mute the speakers (simply muting the speaker volume in Windows, NOT muting the source video or turning it's volume down.)

That has always worked. Until now.

Now, I see I now have an "Audio Input Capture" option. Golly gosh, something new. But nothing works there. No matter how I set it up (yes, I know about advanced settings) I can't get anything but noise to register on the audio input capture meters. "Desktop Audio" meters show audio if Windows speakers are not muted, but nothing if I have Windows speaker output muted - no audio being registered. It used to show the volume of the video being recorded regardless of the machine's speaker output volume.

If speaker output is muted, record and playback shows video but no audio.

If I unmute Windows so I can now hear the audio coming out of the speakers, audio reappears in the recording.

Yes, I've tried every setting under "Advanced Audio Properties" for both Audio Input Capture and Desktop Audio - "Monitor Off", "Monitor Only (mute output)", and "Monitor and Output"

Prior to changing anything, it came up with Desktop Audio in the "Monitor Only" setting, which I would guess is how I've been running it for the last couple years, and also makes sense for what I want to do.

So... I can plug in headphones and just set them aside as a work-around, but it seems like either I'm missing something or something is not working as intended.

Anyone know what button I'm not pushing?

Thanks,

Todd

Thanks, here you go. And I"m afraid I DO save directly to MP4.... Was not aware that was an issue, what I'm doing is far from mission-critical (just archiving local school board meetings) so did not think about it...

Use the Auto-configuration Wizard and apply the recommended settings. Restart OBS and test again.
Run OBS as admin.
Check the GPU driver version. Do not update it from windows update. If you need or think may help, do a clean install:

Win11 has it's own plethora issues.

Thanks, I greatly appreciate the help.

I tried the autoconfiguration Wizard approach, no change. Just for the heck of it I found the version of OBS I was using before (27.2.2), uninstalled/reinstalled that version.

That did not bring me back to where I was a week ago, unfortunately...

I reviewed the GPU driver update process and decided it was just too extreme to be worth it at the moment. The machine is almost brand new - it's a Lenovo Flex 5 I just purchased a couple months ago, came with Win11, and has been working beautifully in all respects except this one.

Perhaps the GPU update might have fixed this problem, sorry I can't provide test results on that, but for now I'm just going to plug in a pair of earbuds and stick them under something whenever I'm using OBS to record streaming video.

Maybe someday some future update - to either OBS or Windows - will restore my ability to record with the speakers muted, but in the meantime I've got a simple fix that works so I'll stick with that.

Thanks again for all the help!
