"Another new feature in 2.048 drivers is the possibility to upload SF2
sound banks, but it's still very limitedbecause only 2MB, 4MB and 8MB
SF2 2.0 banks can be uploaded. In fact, it's a long-awaited option
because basically Aureal ARL format is plainly the SF2 2.0 but with its
own addressing system."

1) Why samplerate is missing in soundfont_sample_info_t ?

The samples in au30gm.arl have different samplerates.

2) How can I create a stream_t for each voice in snd-au8830-synth and
use those vortex_adbdma_**** functions in snd-au8830 modules (using
ADB instead of WT) ?

3) Refer to
http://www.mail-archive.com/alsa-devel@lists.sourceforge.net/msg11719.html

Is it possible to use adb to play the sample loop using scatter gatter
DMA ? ( by adding a flag in stream_t to indicate the sample has a loop )


4) Can those snd_vortex_synth_alloc(), snd_vortex_synth_free(),
snd_vortex_synth_bzero() replaced by kmalloc(), kfree(), ... instead of
implementing a Memory blocks Management system with those fuctions in
util_mem.c ?
