I thought I'd let people know how things were going with this problem I 
had (ALSA getting confused over the presence of both my onboard sound 
and my external USB<>MIDI adaptor.

Due to other difficulties with the laptop, I backed up my data and 
installed Debian Etch, then upgraded that to Lenny/Sid.

Since then, the system has had no problems whatsoever with sound. 
Perhaps some of my difficulties came from the accumulated cruft of a 
six-year-old Linux installation that had been repeatedly upgraded simply 
by changing repositories and updating ...
