some sounds not working with new sound files,

hi guys,anyone any ideas on why sometimes my gear down sounds dont work,also flaps ect sometimes dont work,
cheers steve d

Are you using PMsounds?
I think you can select/deselect each sound separately. Maybe an issue in the settings of PM sounds

Steve,
Sometimes it is the sound that is associated with the particular panel. So if you have a 3rd party panel and sound installed, it could be a hit and miss thing. For instance, if you are using the PMDG aircraft, but using a 3rd party panel, some PMDG sounds won't work. Then there are some sounds that are just plain annoying like the flaps sound on the 737_cfm56_the_real_deal_version_2.zip. Or they are for me anyway.
