I'm surprised it's returnable, best of luck with whatever works. Let us know when you get it running. I'm sure you will.

Same thoughts here. Most decoder manufactures want to handle warranty problems on a one on one with the customer.
I didn't buy from Soundtraxx, i ordered it from EBay.

You never said that in your first post but you did say it is returnable. You are lucky.

If you ever fall over in public, pick yourself up and say “sorry it’s been a while since I inhabited a body.” And just walk away.
I keep an old MP-3 player at the bench where I do my decoder installs. I use it to check the sound output of speaker assemblies before I install them into the locomotive.
By playing a "wide dynamic range" piece of music I can get a pretty good idea of how the decoder will sound after it has been installed.
You can get a 1/8" phone plug and solder brass probes on to the wires. I had an old pair of earbuds and used the wire/plug from that.
While you wait for your replacement decoder you can poke these probes on to the traces of the PC board to make sure the speaker and connections are working on the motherboard before you plug in the new decoder.

Update, it was the decoder. I got another and all is well! You can see a video of the loco here: https://photos.app.goo.gl/busDaf5eoUTZKTov7
Thanks for getting back to us. Sometimes we hear nothing and sometimes we here a thank you, without identifying exactly what fixed the problem.
