I use an Acer C720 Chromebook running Linux to drive my virtual piano software.  I had no complaints with it&#x27;s on-board audio performance, but after reading multiple exhortations on the internet about how much better external soundcards are, I bought a $5 USB soundcard widely available from multiple vendors on ebay.  OK, I can just barely hear an improvement over the on-board.  It&#x27;s better in the sense of &quot;significant&quot; (ie definitely there), but it just isn&#x27;t a material difference to me.<p>If I&#x27;m that deaf to the differences between these two sources, I&#x27;m curious if people think the UCA202 will change my life?
