This is a known bug. Low sample rates seem to cause a strange buffer 
underrun condition in direct relation to buffer/fragment size. The 
workaround is to increase the buffer size until it stops. This can be 
easily done on such things XMMS plugins, but on something like Maelstrom 
you'd probably have to hack the source. ;P

Hey, does the Vortex lock the codec at 44.1/48khz at all times? I 
remember everyone complaining about when using S/PDIF on an SB Live, the 
codec is always locked at 48khz, recording 44.1khz audio is upsampled to 
48khz, then back down to 44.1khz if you're recording at 44.1, and the 
same thing is done on output. Untouched 1:1 digital output/input is 
needed for real studio use. Apparently the Vortex IS capable of at least 
outputting untouched digital output, including outputting AC3 to an 
external decoder. Do we have any clue how S/PDIF works at all?
