MyFirstMemoryDotOrg: "Nothing professional. Just no hissing." Yet you're not going to achieve anything but poor audio quality (in comparison to more robust units), from systems DESIGNED to be substandard in quality. This, me thinks, is what David was alluding to -- and I tend to agree.
The harsh reality is, unfortunately, technology while amazing has limitations relative to purpose. If your purpose is to throw anything up on screen under a belief that content will override poor quality, then inexpensive gear should suffice. But for a few dollars more, however, better product control can be had by using equipment capable of delivering higher production values. As it stands now, issues like over-saturated audio gain (hence, "hissing") is an unavoidable element when using cheaper gear. Thus you may want to consider upgrading to a level that better suits your purpose, or deal with the "hissing" as unavoidable. Hope this helps.
