Experiment 1:
-------------

Load the 25MB piano soundfont file:
 $ asfxload /tmp/WST25FStein_00Aug14.SF2 
 $ cat /proc/asound/card0/wavetableD*
Device: Emu10k1
Ports: 4
Addresses: 65:0 65:1 65:2 65:3
Use Counter: 0
Max Voices: 64
Allocated Voices: 0
Memory Size: 134217728
Memory Available: 108226960
Allocated Blocks: 45
SoundFonts: 1
Instruments: 4078
Samples: 44
Locked Instruments: 4078
Locked Samples: 44
 $ wget http://members.aol.com/myworks/r-c-no02.mid
 $ aplaymidi -p 65:0 r-c-no02.mid
In this case, you can hear music from the Audigy 2 ZS.

Experiment 2:
-------------

Load the manufacturer's Standard GM Midi file:
 $ asfxload /etc/synthgm.sbk 
 $ cat /proc/asound/card0/wavetableD*
Device: Emu10k1
Ports: 4
Addresses: 65:0 65:1 65:2 65:3
Use Counter: 0
Max Voices: 64
Allocated Voices: 0
Memory Size: 134217728
Memory Available: 134213632
Allocated Blocks: 1
SoundFonts: 1
Instruments: 569
Samples: 152
Locked Instruments: 569
Locked Samples: 152

 $ wget http://members.aol.com/myworks/r-c-no02.mid
 $ aplaymidi -p 65:0 r-c-no02.mid

In this case, there is total silence from the Audigy 2 ZS.
