I trying to set the PMDG_eng_fail.wav sound to work with PM Sound, but If possible just one or two times sounding the aural alert and not continuos...just to alert me

PS i am using this in PMSound, but goes continuos until i clear the fail...

pmdg_engfail, 0B6B, .0, ON
pmdg_engfail, 0B6B, .1, ON

Thanks in advance
