no sound with 2.4.23-ben1

[Bill Carini <crisbill@lightlink.com>]

I'm not getting any sound on my G4 tower with the 2.4.23-ben1 kernel.

Here's an excerpt from dmesg (the "Can't request headphone interrupt...
enabling all outputs" are messages I've always seen with older kernels
when the sound was working).

------------------------------------------------------------------------
tumbler: Can't request headphone interrupt
tumbler: Headphone detect IRQ not found, enabling all outputs !
AE-Init tumbler mixer
PowerMac Tumbler  DMA sound driver rev 016 installed
Core driver edition 01.06 : PowerMac Built-in Sound driver edition 00.07
Write will use    4 fragments of   32768 bytes as default
