Another thing that can happen with digital recording if resources get squeezed is that you miss some samples. I have a Dell Dimension from around the late nineties that makes great audio recordings unless there is a fairly intensive file access while the recording is in progress. It creates an effect similar to what might happen if audio tape slipped in the capstan assembly. It is a very tiny flaw in the recording that one notices. Since the Raspberry Pie wasn't meant to be a full-fledged office work station, I wouldn't be surprised if one didn't get occasional hickups like that if using a USB sound card. Those samples absolutely must go somewhere and if the bus isn't there right then, too bad. A work mate of mine has a couple of Raspberry Pies, one of which he uses to play audio on and he reports things are not quite right, but allmost. He is not trying to run speakup, but use the Pie to play a media stream from his Microsoft Media Center.
