It would be very useful for me to be able to do some basic Sonar tweaking from a remote computer. I've used Team Viewer and Splashtop, both of which are applications that allow me to see my home computer from a smartphone or work machine. But I've never been able to make the audio work. Splashtop, for example, explicitly states this should work, but it doesn't for me. 
 
Of course, I assume the reason for this is because I am using my own M-Audio interface instead of whatever Splashtop/TeamViewer is expecting the audio to come from. But I'm wondering if there's any way to make this work by either editing something on the PC or within Sonar itself. Any suggestions?

I really can't see any way to do this myself. There will be bandwidth limitations and syncing up audio and visual could be a nightmare. I guess it could be possible as high framerate video games can be played over the net, but havent heard of anything... Can you not install Sonar on your remote computer and copy the project files across? You will still need a half decent audio interface on your other PC.

I don't get why it wouldn't be possible. After all the processing is said and done, in the end there's just a stream of audio squirting out of some portal to a receiver, right? Isn't it just a matter of siphoning off that stream to a different portal for a different receiver?

I don't really know what you (or I) are talking about, but it is difficult for me to see how any audio device whatsoever would be involved. Would not the audio data stream just be transmitted between two computers, and the only audio data to sound conversion would occur at the remote computer when you try to listen to the sound. If you had drivers for some device on the remote computer, you could hear the sound there. The problem from Sonar's point of view (on the host computer) would be how to package the output to send it to the guest. Normally it would send it to your audio interface, but it would need some location and interface to send it to the remote computer. Some type of virtual audio cable software would have to replace your audio interface, or you would have to do a loopback from your audio interface on the host computer to a transmit buffer to be sent to the guest computer audio data in stream. Lacking that kind of handshaking, you would not be hearing the audio remotely because it would be playing over your audio interface miles away.

Well, is it possible to set up the computer to route audio out to the default audio interface that came with the computer, instead of (or in addition to) my high-end sound card, for the purposes of transmitting it to the remote computer? I mean, these applications claim audio from the host computer can be heard remotely, I just figured it wasn't working for me because I'm routing to my sound card instead of whatever comes with Windows by default.

That is still the same issue. You do not need to send any audio to any audio interface, sound card, onboard chip set  etc. You only need to send the data that represents the audio. But the software you use to connect would have to provide a mechanism to do that, the way that VOIP like Skype does from your connected microphone,  and the software you were using to tweak the audio (Sonar) would have to have a virtual output that would look to it like an audio output to it. If your remote system controller software will let you play an MP3 on the remote computer and listen to it, that connection probably exists. If it will only let you copy an MP3 file from your remote computer to your current computer and play it on the nearby computer it may not. Most remote control software  will let you visualize the remote screen. If it will let you hear sounds from the remote computer, you need to know how it is doing that. If it is capturing the audio data stream being sent to your onboard sound chipset, then setting Sonar to output to that chipset might work. 
 
To route Sonar's output to the on board audio chipset, you just need to select the on board audio as the mains output.

Im pretty sure if you use WASAPI with the default audio interface on your computer splashtop will send the audio remotely. I've used it this way before.
