I just bought the 2-4-4-2 with sound card. Installed the card but...no sound. Uninstalled card reset to factory defaults, even though I hadn't changed them, got the 16 flashing head lights but still no sound. Checked on JMRI and all CVs seem to be correct (& f8). Done all this several times. Soundtraxx suggest trying another speaker but before I take the tender apart I have an idea. Can I swap the sound card in the Bachmann Whitcomb to check if I have a fault on the card or with the speaker? They look the same but I don't want to do any damage.
Any help appreciated.
