Lee Revell 9529a5bae1 [ALSA] emu10k1 - Use 31 bit DMA mask for Audigy
Modules: EMU10K1/EMU10K2 driver

It appears that either the Audigy DMA engine or the Linux kernel cannot
handle 32 bit DMA with this device.  Problem manifests as noise when
using more than 2GB of RAM, possibly only on 64 bit machines.

The OSS driver actually uses a 29 bit DMA mask for both devices, this
seems like overkill for now.
