And it should be 256 * sample rate of AIF1.

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.

The lock is needed for the refcount handling, so move it locally. The calls in emux_seq.c are already with the mutex, thus they are replaced with the version without mutex lock/unlock.
