I wasn't hearing any click sounds in the VC and thought that I had read that the issue was fixed in v1.4

I discovered that the sounds are disabled in the DLL.XML and manually had to change Disabled>False<Disabled in order to hear the sounds.

Notice default still shows as True.

<Launch.Addon>
     <Name>Captain Sim 757 Sound</Name>
     <Disabled>True</Disabled>
     <Path>Captain_Sim\757\cs.sound.dll</Path>
</Launch.Addon>
</SimBase.Document>
