I recently purchased a Bachmann SP Daylight #4449 RAILFAN - GS4 4-8-4 - DCC SOUND VALUE (HO) locomotive (model #53101.)  I'm trying to figure out exactly what Sound Decoder is used in this model.  I use JMRI (ver 4.6) Decoder Pro on a Programming Track to program all my DCC decoder equipped locos. When I use it try to identify the decoder used in this loco, it lists a dozen or more different SoundTraxx Tsunami profiles, none of which are identified as a GS4 4-8-4.  I've tried a couple of the various decoder profiles but each one (so far) has left me with no sound from the locomotive.  When I reset the decoder to factory defaults, the sound functions return but I would really like to modify some of the options.  I just can't seem to find the profile that works with it.  Does anyone have any insight into which profile I should use?
