DSP Studio not working with Video content?

You have to use the WDM driver to pipe audio from the built-in web browser through MC, otherwise it goes through the system mixer like any other web browser.

You sure about that?

This post from 2010 states that video DSP was implemented natively:
https://yabb.jriver.com/interact/index.php?topic=56123.0

No mentions of WDM/virtual input/output routing requirements are made, but then again the option to enable the feature is not located in the referenced place, either.

So this feature's been changed apparently, but it seems to be an undocumented change (?)
Would be nice to have some more officially documented clarity on how it functions now.

To be clear when JRiver plays a local video file (i.e. a file on your computer) DSP should work normally just like with an audio file.  I use that functionality every day.  However, video played in the embedded browser does not (and has never to my knowledge) passed through the JRiver DSP chain without using the WDM driver as a loopback solution. 

So if you're seeing no DSP on browser based video (even the browser embedded in JRiver), I would expect no DSP without using the WDM driver.  But if you're seeing no DSP even when playing local video files then something is odd, as that should work the same way as audio. 

If you are seeing the second case, say more about what happens when you play a video file.  You should see the audio information in audio path, etc., and that might tell you where things are breaking down.

For the embedded web browser (Edge via WebView2, Chromium via CEF, etc.) yes. It's an external component even though it's integrated into MC it's still external hence the only way to pipe any audio played in one of the embedded web browsers is the WDM driver on Windows.

Playback of actual/local video files should go through the DSP engine, yes. As long as it's not within the web browser, of course.

NannySt:
Hey guys, thanks for the recommendation to check the 'audio path' (cogwheel beside the playback position bar for anyone looking).
That provided the insight I needed to diagnose:
Turns out the video in question is using eac-3 (Dolby surround); it is an Atmos mix with 6 channels.

I updated my app version and it now passes the EAC-3 audio through the DSP studio, but suddenly the stereo mix is gone and I'm just hearing the sides! (Background is there but no dialog track)

So still fiddling with it a bit. Close to having it working though, it did this before I updated the program and I got it to work with a combo of audio device+output settings but forgot what I did.

Much appreciated!
