Looks like audigy emu10k2 (probably emu10k1 - sb live too) support two modes for DMA. Second mode is useful for 64 bit os with more then 2 GB of ram (fixes problems with big soundfont loading) 1) 32MB from 2 GB address space using 8192 pages (used now as default) 2) 16MB from 4 GB address space using 4096 pages Mode is set using HCFG_EXPANDED_MEM flag in HCFG register. Also format of emu10k2 page table is then different.
