Hi again, try the following options line... options cs4232 io=0x530 irq=5 dma=1 dma2=0 mpuio=0x330 mpuirq=5 synthirq=-1 synthio=-1 you might also try different combinations or setting irq and mpuirq to values of 5 or 9. That's the values windows seems to give this card in most cases. After all you can still try using ALSA. Andre.
