In case of anyone else following this issue: i contacted tech support, who were very helpful, and it turned out that the problem is because i installed camtasia studio on an msi laptop, because msi laptops often come with nahimic audio, the source of this problem.. I cannot record mic and system audio with camtasia studio recorder (records screen with multiple audio) it s. ays "system audio setup failed" with nahimic off (i.enot running) the recording is performed without any problems !. I made this video because i just realized it and wanted to pass the word :d please note that this video will not work for everyone!!! if it doesnt work for you then try updating your sound drivers.
Since camtasia only recognizes one input source, that source would have to be the line in on the motherboard to capture the system audio, and then i'd have to set up something like audacity running in the background recording the usb vocal mic. then i'd have to import the vocal into the camtasia session after the fact.. Camtasia studio gives you the tools to record your computer screen and then turn those recordings into professional-grade videos. in tools to enhance and improve the audio quality of your. Tried v8 and it didnt record system-audio on any of our three computers, google for hours and the only answers i found was “yeah, we know v8 has big issues with win xp and vista – but it works with alot of win 7 computers”. downgraded to camtasia 7.1 which i worked alot and never had one single problem with before and voila, it works..
