Bachmann SD70ACe DCC/Sound issue

[Quentin]

I have a brand new Bachmann SD70ACe with DCC and SoundValue. Just put it on the track, programmed it on my EZCommand DCC controller (yeah, it sucks), and ran it on a small(er) layout. As soon as it hit the track, I knew something was wrong because there was no sound. I tried unmuting it - no good. I know the speaker is on the bottom of the fuel tank, but other than that, I don't know anything about this locomotive. What should I do? (I'd love to NOT send it to Bachmann)

Thanks,
Quentin
