Default Reaper asio to WDM apps, best solution ?

I have tried several different workarounds to get
Reaper to send audio to a screen cap program, but none has worked so far.

VB cable, VB hifi, and Asio Link Pro

Asio link pro looks the most promising, and I see people using it cool
as a cucumber with Reaper.. but when I try to launch it's asio
driver in Reaper.. I keep getting the error "asio clock has overflowed"
and it wants to reset, doing this over and over until I need to terminate
Reaper... I searched on the error and found virtually nothing..except
the suggestion to untick "close audio device when stopped and application
is inactive" which I did. Still get the endless reset message from
Asio link app. Anyone use this to redirect asio audio smoothly?

or anyone have a solution that works much better..?

Synchronous Audio Router might be capable of doing what you want: http://sar.audio/

yes. I chose my main asio audio device as its reference device and then created a bunch of virtual input and output pairs. I then assigned those in other audio applications and was able to route audio between them.

Configuration is a bit unintuitive:
  1. launch Reaper
  2. select SAR as the asio device and then close and re-launch Reaper
  3. go back into audio device prefs and open the asio config window
  4. select a reference asio device (your main audio interface)
  5. add virtual input (record) and output (playback) pairs and lable them to reflect their future use for other audio apps (those apps must dispose of an audio device selection option like OBS, AIMP, mp3DirectCut and others)
  6. close and re-launch Reaper again and then add the newly created inputs and outputs to the range of enabled ins and outs.
  7. launch other apps and select their corresponding virtual in/out.

SAR is different from other virtual audio drivers in that it can aggregate the user-created inputs and outputs with those of the regular hardware audio device so that all of them can be used simultaneously. VB-audio cable alone requires you to select it as Reaper's only audio device leaving you with no access to any other audio device.

Be aware that SAR's virtual audio ins/outs will only be available while the associated app it's configured in (here: Reaper) is running! Else, the audio apps will fall back to other in/outs.

you can also use Voxengo Recorder VST plugin (in addition or independently from using SAR) to get audio from Reaper to OBS by inserting Voxengo Recorder into one or more tracks or the master track in Reaper (multiple instances, if desired). Voxengo Recorder allows you to output audio via a different audio device than the one selected in Reaper's audio device prefs. This plugin adds some (configurable) latency, though, while SAR doesn't add any latency at all.
