... a sound card with lowlatency capability or experienced problem with your actual OS and don't want to modify your hard drive then you should give it a try.
For example, I setup a 2009 PC with Jamulus OS and used a recent sound card like Zoom U22 and an old one UCA202 Berhinger ... Sometimes the internal hardware of your computer is enough for using with Jamulus ! Every USB class compliant sound card should work with Jamulus OS.
