[SG2_Wasy]

ok, i did all of above, ie

1) made aircraft.common.prs using your quoted text.

2)added the wav file and named it "diving_17_81a.wav"

3) Added the text "samples/diving_17_81a.wav"
"presets/sounds/aircraft.common.prs" to the filelist.txt doc.

4) When i tested the game i got no dive siren at all from the Ju87.
hock:

Thank you loads for helping though, i'll send a Pm to wasey and see if he can help.

May be format of sample is wrong - need PCM 16bit mono or stereo (mono is better)

P.S. For changing standart sample don't need adding presets......
