I tested it on 2.6.10 with alsa 1.0.8 and have found what looks like
a possible problem with the emu10k1 synth support.
Soundfonts still load ok but despite mixer levels being ok
("Music=Master=...etc...=100%") there is no sound at all when using the
emu10k1 wavetable synth, e.g. with aplaymidi.

PCM playback and recording both seem to work ok.

Excellent work!  Very well done.
