does anybody know of any method of creating a panel/gauge which plays wav or mp3 files by clicking a button, Similar to FSPassengers

I can only speak for C-programming and I know of two ways to do this. If you download sd2gau29.zip it contains the source code for adding sound to a gauge. Alternatively, you might like to look at FS2Crew's Extreme Audio Module. This still requires C-programming skills but it's easier to implement than the raw DirectSound code provided with sd2gau29.zip.-Dai

I also offer a custom XML->C sound module for payware companies. It will handle up to 200 .wav files.Doug Dawson has an XML->C module that's ideal for freeware developers.

Hi,as Bill said, you can use Dougs excellent XML sound interface , if you want to built in a sound in your XML code. The file at AVSIM is "dsd_fsx_xml_sound3_382.zip".Secondly you can go with a .gau file developed by R.L. Clark. This program is for FS9 but works perfectly in FSX also. It supports mp3, WAV,MID,WMAformat. This is a excellent way of building your own little sound panel. The program allows you to select per mouse click out of any folder your favoured sound/music etc.. Can be done during your flight in FS. So, a wonderfull way to hear your music during a long distance flight. The file at AVSIM is "pswtch2.zip".Dietmar
