The UA-1A has 5 interfaces: one for output, one for no output, one for input, one for no input, and one for describing the other four. This is required by the USB Audio Specification.

Any of the following may help (or not): - Please check that DMA transfers for the harddisk are enabled (you can check this with hdparm). - If you use KDE, disable the automatic checking for a newly inserted CD. - Many graphics card drivers disable interrupts while drawing. In this case, don't do anything that draws to the screen while playing/recording sounds. (This may include moving the mouse. Ouch.) Some drivers may have a setting to run more cooperatively. YMMV. - Make sure you have as few as possible background processes/daemons running when playing/recording.
