Downsample Output?

Is it possible to send 16-bit / 44.1 kHz audio to a hardware output when the Sonar project is otherwise running at 24/96?
 
I'm trying to use screen-recording software (Camtasia) to capture and share my Sonar sessions.  Unfortunately, my projects are usually 24/96 and Camtasia only supports 16/44 and below, with no option to downsample higher resolutions on the fly.  I've tried various loopback strategies through my Lynx AES16 / Aurora 8 AD/DA with no luck.
 
But then it occurs to me, if Camtasia can't downsample the input, maybe Sonar could downsample the output?  I tried inserting Izotope Ozone on the hardware output channel, but it doesn't offer sample rate reduction - only bit depth reduction.  I'm unaware of any plugins that do this, or if it would even work.  I'm sorta thinking Sonar locks all of the assigned hardware outputs to the project resolution, no?
 
Any advice is greatly appreciated.

    Could you patch the output to an input on a separate audio interface and get Camtasia to use that as a source?

    I am not sure of the capabilities of your interface, but WDM mode would be something to try to allow multiple programs to access the audio interface. You may need to fiddle with audio buffer to get a usable latency on a screen capture (if that route will work).
     
    You can also try WDM mode from SONAR through the onboard audio (fine for playback, but terrible for recording), which may give Camtasia a better tap-point.

    Voicemeeter can handle multiple Bit Depth/Samplerates from/to different programs. Not sure if it can handle 96khz but I'm pretty sure it can.
     
    Essentially Voicemeeter works as a virtual digital Mixer/ASIO interface for exactly this type of program to program chicannery. It's a "donationware" program so "free" to use. You just toss them a couple bucks if you find it useful.
     
    Google it.
     
    Cheers.

    PS: Here's a vid I created about routing Sonar into Mirrilis Action (another screencapture program) using Voicemeeter.
     
    https://www.youtube.com/watch?v=SXEtm5_M9HI
     
    It's looooong (almost 5 hours) and was my first vid ever (just as a test) but I broke it up into clickable chapters and cover all of the routing/setup wackiness. I don't use Camtasia (wish I could afford it) but many of the principles should be the same as far as audio routing and I prattle on about Voicemeeter itself quite a bit.
     
    Might be useful.
     
    Cheers.

    There's been good advice already, but I have an interesting twist on doing videos and audio that will be the "Friday's Tip of the Week" for tomorrow. Stay tuned. It's a technique that has made my video life a whole lot simpler/easier.

    I don't have a separate interface but the AES16/Aurora 8 appear to support multiplexing (if that's the right word) - any combination of bit depths and sample rates on every channel.  So, I tried a D/A to A/D loopback and was surprised it didn't work.  Camtasia stopped (or crashed, depending on its settings).  Admittedly, I don't know all the ins and outs of the Lynx, or ASIO, for that matter - never really had to.  I should probably do some research.

    I've seen this recommended a lot.  It looks incredible, especially given the "price."  Admittedly, my workstation is my baby and Voicemeeter sorta scares me - 'fraid I'll break something - even after watching all the videos on YouTube.  But I haven't seen yours yet.  I'll check it out for sure.  Thanks!
     
    Oh, and yes, Camtasia is stupid expensive for what it does.  I'm open to alternatives.  But so far, Camtasia was the only one - I've demo'd three now - that would work at all with my setup.

    Oh, you're such a tease!  :-D
     
    Can't wait.
     
    Thank you, everyone!  Lots to digest here.
