Is there really no way to switch between your headphones and desktop speakers with out going into the connect software? I just upgraded from the x-fi titanium and all the ports could work at the same time.
Well, old PCI X-Fi and it's PCI-e version X-Fi Titanium don't have separate headphone and line outs.
So neither card's hardware, nor software could have even told the difference regardless what was connected.
Z-serie and newer have headphone and line out physically separately.
For Z-serie there's
SBZ Switcher, which can be used to automate switching between headphone and speaker behind hotkey.
I don't know yet similar third party application for AE-5.
You better contact Creative, so that they might add hotkey functionality for that into future drivers.
Though in Z-serie that output configuration setting is stored in Windows registry.
So if AE-5 does it similarly it would be possible to use registry monitoring tools to find key for that and corresponding values.

After that it shouldn't take that much web search for how to make for example batch-files for changing that key and then add hotkeys for shortcuts of those bat files.
Myself don't have AE-5 so can't check that.
(and likely don't upgrade from ZxR until head and ear shape customizable HRTF "Super X-Fi" products come out)
Presume you upgraded from Titanium HD, if so how does the AE-5 compare?
X-Fi Titanium HD has sense function in headphone jack which makes hardware route signal to it disabling RCA line out.
With software having nothing to do with it.
