To play the midi icons, you must have a midi synthesisor built into your sound card (I know it seems obvious, but newer sound cards rarely have this).  Also, you must first initialise the midi voices, using a seperate midi program.  That would eliminate the message "Getting OPL3 - Initializing voice 0 with undefined instrument".

The Soft OSS Mixer is NOT an option.  It works by first scaling all input streams up to somthing like 44kHz, which even without mixing places a large strain on the cpu.  There were some messages about this recently which you could check the archive for.

Ok, this is interesting to me, as I have a soundcard that provides 2 dsp interfaces, dsp0 and dsp1.  I CAN'T get the auditory icons going for some reason though :(.  Did you do anything other than what you just described above?

As far as I can tell what you need to do is play a small midi file before you start emacspeak with the midi icons.  That is known to often work.
