But how did you ever come up with needing the R105155 since it is not
listed as an audio driver for the 2400 model?

Thought you'd never ask :)

Actually I used Driveragent to do a scan on the 2400 - it revealed
said driver needed. I couldn't download it because I have exhausted
all the machines I can use (10) Driveragent for (on past machines, now
long gone).
