ESS1888 Internal

I have sound card ESS1888 (internal) In Linux I attach this startup command: /sbin/modprobe soundcore (Compiled as module !) /sbin/insmod uart401 /sbin/insmod sb io=0x250 irq=10 dma=1 dma16=-1 /sbin/insmod mpu401 io=0x320 /sbin/insmod v_midi It's work, but I have slow-voices in output and on some time report: Sound: DMA (output) timed out - IRQ/DRQ config error? What's happen ? Linux 2.2.16 #3 Thu Jan 11 13:08:57 UZT 2001 i686 unknown
