SubjectOops in aci.c (sound driver)
Hello Hackers,

I compiled the kernel 2.0.11 with module sound support for my Miro
PCM1pro, (MAD16 wih lowlevel driver aci.c). After inserting the module
with

insmod sound.o

following violation occured:

The modules remains in uninitialized in memory.

When I install the sound not as a module, everything works fine!

Any ideas?

P.S.: How can i switch the amplifier of the soundcard on?
