There seems to be everything in your post except the kernel version. The
ability of linux to produce any sound on my 9600 has varied with the kernel
version. The PPC kernel maintainers have been restructuring the sound
driver with the result that some official kernels do not support sound on
older Macs. You can try:
- getting a kernel from ppckernel.org
- compiling sound into the kernel - this can work when a module doesn't
Various other people have indicated that the mixer settings for internal
sound can be defaulted to zero - so look at this with aumix or similar.
