Small update in case anybody might be interested.
Adafruit has not been very responsive or helpful in troubleshooting/resolving the sound board issues, but I eventually got it working on my own. There were a number of separate issues involved. First, apparently one of the amplifier boards is bad. I bought a 2210 all-in-one soundboard (integrated amplifier) and at first it didn't work either. It turns out the WAV files need to be PCM-encoded at 16-bit or less. After I changed the sound file encoding the 2210 board works fine. Back to the 2342 and it now works also, but only with a different amplifier board (fortunately I bought multiples when ordering and could swap parts out). The first amplifier I had wired up produces no sound, which is why there was activity on the sound board but nothing from the speaker. A different amplifier board resolved that problem.
Another issue, and I don't know if it's an Adafruit thing or another dorky Apple thing, but when deleting sound files from an Adafruit board using Mac OS X the files don't actually get deleted from the board. Instead they get moved to a hidden .Trashes folder which still occupies memory space on the board. The more sound files that get deleted from the board while troubleshooting, the less and less space becomes available for new sound files until....no more space available, even when there are no sounds saved to the board. I discovered this using a Windows File Explorer and found the hidden folder. After manually emptying it I could then save sound files to the board again.
So I've now got all 8 sound effects written to the board, and more-importantly can hear them from the speaker. Circuit breadboarding can finally be resumed.
