Hi there, I'm a newbie.  I just threw away some money on an Edirol UA-30 USB audio interface which sucks and is WAYYY too noisy.  I did a side by side test with running sound straight into my minijack (on a G4 Powerbook) and the sound was sooo much better.
So...  why do I even need a soundcard?  I've heard that M-Audio makes decent devices, but to me they look just like the cheap, plastic piece of crap I just bought.  Is it just that Edirol sucks?  Did I get a bum device?  Are other devices that much better?  Any help is greatly appreciated.  Thank you.
