No sound from speaker - new audio option pack

[Oli Dainton]

Hello all.

I have the 2018 Panzer III with motion and audio packs.

Drive motion is now working as expected, motors set up as a single stick operation.

I have wired the audio module as per instructions, using the y-leads to feed motors and audio module from channels 1 & 2.
The 3 position switch wire is connected to channel 7 of receiver, I have no other channels connected yet.
I am using a Futaba T7C transmitter and FASST receiver.

I have set the three position switch to channel 7 in the menus.
To test this I connected a servo to channel 7 and sure enough the servo moves from full travel in one direction to centred to full travel in the other direction when I use the 3 position switch.

However, when I turn on the power to tank, I hear the single beep, as expected, but no matter what I do with the 3 position switch, I don't hear any of the sounds from the speaker.

Presumably the audio module just reacts to a full travel signal from that channel to trigger sounds, and the servo proves that is being sent.

I haven't run through the calibration steps as these appear to only be relevant to throttle based sound feedback and the manual states I should be able to play any of the sounds prior to doing any calibration.

Any ideas?

I've always gone through the calibration process for every new installation, otherwise the system doesn't know the receiver signal values of the three switch positions.

Hi Adrian
Unfortunately the calibration process also requires the use of the three position switch. I only hear the beeps during this process as well.

I have seen other threads about sound modules, but since the module is receiving a servo signal correctly for the switch and the speakers do actually work, what else can I do?

Sounds like you may have another wiped sound card, as per the message here on Friday.
