Current Behavior
Currently, when using Application Audio Capture, I can record the output of just that application while filtering out other applications. However, for applications that output to multiple audio devices at once, this can cause problems.
Genshin Impact, DEATH STRANDING, and Call of Duty: Modern Warfare 2 are three such examples, as they can output haptic feedback to the DualSense controller via the Wireless Controller audio channel. The Application Audio Capture plugin is picking this up at the same time as the games themselves.
The plugin needs another property to decide which device outputs to capture audio from for a specific application, not just mix all of them at once.
The current workaround is to output the game to a different audio device and only capture that audio via the Audio Output Capture plugin, but that defeats the purpose of using the Application Audio Capture plugin.
P.S. I've also tried capturing the Wireless Controller via Audio Output Capture and inverting its polarity to try to negate the issue... sadly didn't work. :(

Steps to Reproduce

You could fix that by using a app called virtual audio cable to mix the 2 audio streams together then pick that as your audio source.... At least until OBS fixes this or more accurately adds this as it's kind of new and only PlayStation games do it.
Virtual audio cable is a godsend, it can make the "impossible" happen. It's free, easy to use and they make a couple helpful apps for audio too. I highly recommend it.
No log file provided, and you mention the third-party audio capture plugin, which means this is unsupported by us and would need to be reported to the plugin developer.
As a log was not provided, we cannot investigate further. Please provide a log file if this is the internal application audio feature, and not the third-party plugin, and we can take a closer look.
I've included a log file, and this time I'm using the beta audio plugin that is included with OBS Studio 29.0.2, deleted and reinstalled to make sure. Look for when the plugin targets GenshinImpact.exe.
Reopening. I am still unsure if this is something we can control on our end, but I will leave that to people more familiar with the API itself.
I'm also experiencing this with The Last Of Us. I imagine Cyberpunk would also have this but haven't tested it yet.
