Hi, I was ill.

Thanks for your help. But it works only with changes in my tecra Bios:

Bios: Sound chip OS selected -->> All devices
my settings in /etc/modules

soundcore
sound
mp401
opl3sa2 irq=5 dma=1 dma2=0 io=0x530 mss_io=0x538 mpu_io=0x330

afterwards I got sound

But dmesg said

... io 530 is not a YMF7xx chipset and the module was not loaded ..

maybe there is something wron with the sound driver ?

bye Pierre
