1.A fullpath to the media is maybe better in function of what folder you are (in your app) !
this works as well:

SET BELL TO (ADDBS(GETENV('windir')))+"MEDIA\NOTIFY.WAV"
?? CHR(7)

it works also with relative path but the media location must exists mandatory.


2.i gave some solutions (4) to play a sound media in this link:

3.can try also

#DEFINE SND_SYNC 0
#DEFINE SND_ASYNC 1
#DEFINE SND_NODEFAULT 2
#DEFINE SND_MEMORY 4
#DEFINE SND_LOOP 8
#DEFINE SND_NOSTOP 16
 
DECLARE INTEGER sndPlaySound IN winmm  STRING lpszSound, INTEGER fuSound
 = sndPlaySound(getfile('wav'),SND_ASYNC + SND_NODEFAULT)  &&fullpath of wav file
