Expected Behavior

I expected to be able to record audio from my Elgato Video Capture USB device, however, audio capturing fails. Only video capturing works. I will test on a new version of OBS shortly.

Current Behavior

The video feed appears as expected in the scene, however, no audio is recorded. No audio playback occurs in my recordings, nor does the "green audio bar" which shows in the audio mixer indicate any audio is actually playing.

However, when I use the official Elgato software, I get audio playback just fine. Judging by the amount of threads on the OBS forums I've found which have the exact issue, I believe this problem is not me using the software incorrectly, but instead a problem with OBS.

I believe the relevant line from my log is:

14:59:07.499: [WASAPISource::TryInitialize]:[Analog Audio In (Elgato Video Capture)] Failed to get mix format: 88890008

Steps to Reproduce

  1. Attempt to capture audio with a composite Elgato video capture card.

Anything else we should know?

OBS Studio 21.1.0 on Windows has a broken updater. The current version of OBS Studio is 29.0.2. Please update to OBS Studio 29.0.2 and try again. If the issue still occurs, please provide a new OBS log file.

Will do. I believe it happens on newer versions because my laptop (which is running a newer version of OBS) also experiences the issue. I did just manage to find a weird workaround, detailed here: https://obsproject.com/forum/threads/transferring-vhs-to-elgato-video-capture-with-obs-but-audio-not-working.165016/#post-605412

The audio goes away as soon as I edit that configuration window though, so this is 100% not a long-term solution I should clarify.

RytoEX commented 1 year ago

We will still need to see a log of this happening in OBS Studio 29.0.2 or newer. I would also recommend making sure the Elgato software and drivers are up to date.

Kneesnap commented 1 year ago

Updating right now! I'll check the driver version too

Kneesnap commented 1 year ago

The driver version matches the latest version available on the Elgato website.

I have updated OBS to the latest version on obsproject.com, or OBS 29.0.2 The issue still occurs.

Here is the log file from the updated version: https://obsproject.com/logs/oyJzqOGL7e5Bhh0H

Does the same issue occur in Elgato's software?

Kneesnap commented 1 year ago

No, the Elgato software plays audio just fine.

This sounds more likely to be a support request rather than a bug report at this point, Please use our forums or Discord for further assistance.

Thank you!
