1) What value of memsize will need to pass into snd_util_memhdr_new(int
memsize) if au30gm.arl is about 5 Mb ?

2) Do au88x0 DMA (scatter-gather) has any alignment requirement or
maximum size of the samples ?

3) Is it correct to implement functions snd_soundfont_load_arlpatch(),
load_arlpatch() in soundfont.c to load arl ?
