[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.
