It stutters when using mpg123, where a small segment of music is played a number of time before moving onto the next segment. Looking at the code, I see that the DMA is set up in auto mode. I can only surmise that interrupts are not being serviced - perhaps we're sleeping at too high a priority? My machine's bios is set up believing that it has a PnP aware OS, resource allocation is automatic and all IRQs are available for Pnp/PCI.
