"Trial is not usable!"
Good setup configuration
The trial version randomly (1-5 sec interval) speaks "TRIAL" over the audio streams!!
Can easily create a feedback loop that remains at bootup (prior to login) when an app such as Skype has defined one of the "cables" as an output device and "Stereo Mix" is an active "listen" device. Though easily corrected, it is QUITE THE SURPRISE after rebooting and returning at some later time and noticing that the speaker has been spewing white-ish noise from the feedback loop!
OS is Windows 7.
The restriction on the trial version is MORE SEVERE than just only 2 cables, unless you like the female voice repeating "TRIAL"!
