blinking led haedlight in reverse

Also,

Some of the sounders (1662, and 1666) have an undocumented CV49 which if set to 0 (zero) or an even number turns off all sounds,  set it to 1 or other odd number to turn on the sound. A  decoder reset does not change CV49's setting.

When you reset the decoder you set the address back to 3.

I don't have any experience with Digitrax decoders but I have been using MRC sounders with NCE and TCS decoders for motor and light control. I have found there to be a few conflicting CV's. One of the CV's that control light functions on TCS also is used for one of the sounds on the Sounder.   I would check all of the CV's on your Digitrax and look for a CV that is also used by the Sounder.

 i just put in a dz 123 in my bachmann 4-4-0 n scale and a led headlight it ran good , then i puchased a mrc sounder and everything programmed well ,until i changed some of the cv s ,by me changing some of the cvs ,did i change the light output on the digitrax decoder ,when i put the engine in reverse the headlight should go out but it just blinks, like its picking up a pulse. i checked all the wiring for a short but found nothing.
