I don't have a Tsunami-equiped Shay but before I bought my non-sound 3-truck-er I do remember reading a bit about problems with the sound shutting down over about 18V. One of the solutions was to fit series of diodes in the power feed to the decoder to reduce the voltage it sees compared to the actual track voltage.
Maybe try a google search on the subject?
