Mysterious Doorbell Sound Playing from OBS

[npudar]

I have a new mystery. It started last night during a Zoom call. During the call, there was a loud and persistent Doorbell sound playing. (An MP3 of the sound is at the link below.) The meeting host determined that it was coming from me. A quick run of Task Manager found nothing running except OBS and Zoom. I did not want to kill OBS, but I quickly discovered that it was coming from my speaker, so I could just mute myself. When I needed to talk, I turned my speaker volume down to eliminate the sound, and spoke into the microphone. After approximately ten minutes of persistent playing, the Doorbell Sound stopped.

Then this morning during another Zoom call, it happened again. This time, I thought to open my "Ear Trumpet" application which gives me application-specific volume control. I could see that OBS was the source of the sound, and I could turn it off in Ear Trumpet, and still let the Zoom application play its sound.

I checked my settings in OBS, and the only thing I have connected for sound is my Yeti Microphone. I have been using my setup like this for over a year. This just started last night.

It almost sounds like there is some "alarm" or "timer" set within OBS.

Does anyone know what this is and how to control it?

Thanks,
Nick

Please post a log with your issue! Here's how...

OBS Studio creates a log file each time you run it which contains very useful diagnostic information. Without a log file, it's much harder for any support volunteers to figure out problems and your post may be ignored. To upload a log file, go to the Help menu > Log Files > Upload Last Log...

You have a few browser sources, maybe they are playing it. Check the mixer in OBS to see which source is causing it.

I'm not entirely sure how to check that. When the sound was interrupting my meetings, I looked at the OBS Audio Mixer and it only showed my Logi Brio camera and my Yeti Microphone, and both of them were silenced as shown in the "Settings Screenshot" link below. (I also included the Audio settings in that same screenshot.

Interesting... while I am typing this, the doorbell sound started playing again. I opened my Ear trumpet application and took a screenshot of the sources, and you can see in the second link below that there is sound only coming from OBS. The only browser that is open is this one OBSProject tab. While the sound is playing, my Audio Mixer is the same as the first screenshot below.
Here is the link to the log file from just now.
Also, when I immediately restarted OBS, (and changed nothing else on my system) the sound did not play.

Is there anything else I might check?

Thanks,
Nick

Thank you! It got me looking at all my Scenes and Sources more closely, and I found the culprit.
It turns out I had set one of my Scene Sources to be a browser that pointed to a website with a countdown clock. (I use it when I teach over Zoom for class breaks.) When the clock gets to zero, it plays that alarm.

It is very possible that the most recent update triggered the browser website to start the clock when OBS started. My default timer for that site is a 15 minute countdown. And that is consistent with when the alarm would start playing in the past few days. (And it very likely started after the most recent OBS update. This alarm behavior has never done that before, even though I have had that Scene for a very long time.)

To fix it, all I had to do was select the two Browser Source Properties' checkboxes to "Shutdown source when not visible" and "Refresh browser when scene becomes active". That immediately stopped the alarm (which started playing again while I was looking through the Scenes).

Thanks again for pointing me in the right direction!
