I am accessing my home computer remotely using Teamviewer. I am getting audio via YouTube, iTunes, and Abode Audition, but not through Sonar. Audition shows it's output device as Line 1/2 (M-Audio Delta Audiophile). The other available M-Audio output is S/PDIF. My Sonar project's output device shows as M-Audio Delta ASIO Analog Out 1/2 L Delta-AP. Again, SPDIF is also listed. I don't understand the difference in the outputs here. Can anyone explain why everything outputs audio through Teamviewer except for Sonar?

Heh you might want to stop using Teamviewer considering there was a massive hack earlier this month that gave access to your computers including any saved passwords and all files.

OK, well I read into that and it doesn't apply. Anyway, back to my original question.... any ideas?

ASIO does not go thru the Windows mixer. It is direct from Sonar to the audio device.

I see. So is there any way to temporarily re-route my output for when I am accessing remotely, then just change it back to ASIO when I get back to the studio?

YouTube, iTunes, and Abode Audition all use the onboard soundcard. Sonar does not. it uses your Deltas soundcard / ASIO driver.
 
So to answer the question above,
if you want to simply mix, listen, do some editing in Sonar using teamviewer, try switching your soundcard options to MME.
you may need to adjust your buffer settings accordingly but you shouldn't have any problems connecting to sonar and completing common tasks.
MME uses your onboard soundcard: much like YouTube, iTunes, and Abode Audition does. give it a try and let us know.
 
On a side note, recording using teamviewer...that's another other ballgame right there...and too technical to get in to at this time.

Do a search for Beepster's posts on setting up VB Audio's "Voicemeeter" (donation ware). He used it for screen capture of Sonar, but it (Voicemeeter) is essentially a virtual mixer that will mix windows and Asio sources, albeit with (a tad of) latency. I've used it for syncing video and graphic effects to sonar but it's not for the faint of heart and you have to get your head around how it works. I ended up using a second computer for what I needed, but it works. Would be better than mme, imo.

If you are referencing this:
http://arstechnica.com/security/2016/06/teamviewer-says-theres-no-evidence-of-2fa-bypass-in-mass-account-hack/
than (a) that is not relevant to "normal" TreamViewer use cases and (b) that is not teamviewer problem at all
 
If you are referencing something else, please publish the link. You claim is quite serious, many people are using TeamViewer. Its service is running all the time (and it is connected to them). So if there is any real evidence that something "spy" or take over, it will be interesting to know.
 
But I repeat, everything with "mass account hack" is NOT relevant for users without TeamViewer account (and so for most users).

@chuckebaby I tried switching to MME, and messed around with drivers and stuff, couldn't get anything to play, and since it's pretty critical I keep the house of cards that is my studio setup in working order until my fast-approaching album deadline, I decided not to mess with it further.
