I've found that the only non-intrusive way to "add sound" is to play it
as background sound (page options). Setting a link to a music file
behind a button is exceedingly ugly: the player insists on being
displayed (either entirely or as a smaller - but still intrusive and
unnecessary - set of control buttons).
So if you want to play sound behind buttons, link each button to its
own page where the sound is played as background sound. That page (in
most cases) is created as an exact duplicate of the page you came from
(except for the background sound, of course).
Something else to keep in mind: don't link to .mp3 files, but instead
link to .m3u files, to get the music to stream (and start playing
immediately). An .m3u file is simply an ASCII (text) file with the full
path of the file to be played on a line. If you want to play more
songs, just add their paths (each one on its own line) to the file.
And something else: .wav files are enormously large; it's best to
convert them to .mp3. There are numerous conversion programs out on the
web; I use waver.exe.
Then, if you just want a section of the file to play, use xingtone.exe
to cut your .mp3 file into segments; then "re-record" the desired
segment, using smr.exe. To re-record like that, get a (shielded) male
to male little cable and connect the mic-in jack to the headphone-out
jack on your sound card (if you can't find shielded cable, just wind
some tin foil around the cable). Then play the segment in xingtone.exe
while recording with smr.exe (the program can be found under the name:
supermp3recorder).
Xingtone and supermp3recorder are both available on the web for a
nominal fee, as is waver.
Hope this helps.
