[Comm] ISA'шная звуковуха

[Sinom]

Я уже писал, но проблему не решил. Звуковуха ISA = Gravis UltraSound MAX. Ядро 
2.6.5. подгружаю модуль:

# modprobe snd-gusmax port=0x220 irq=11 dma1=6 dma2=7

появляется устройство /dev/dsp но звук не играет, т.к. прерываний GUS MAX не 
происходит:

# cat /proc/interrupts
           CPU0

Куда копать дальше не знаю.
