Engine Noise different when DME added to 172SP

Question

I wanted to add DME to the panel in the stock 172SP and so saved it as a new plane after adding the instrument. Nothing else was changed. Now the engine noise is completely different than the stock 172SP.

Answer 1

The default 172 may have had custom sounds. Did you copy the entire default Cessna 172 folder before making your changes to the panel?

Here are the steps I used:

In Plane Maker I selected >File>Open>Aircraft>Cessna172SP>Cessna_172SP.acf>Open Aircraft>Added DME to the panel>File>Save As> Then renamed aircraft.

In X-Plane: I open this aircraft and note the new engine noise.

 

Thanks for your help!
