Dear Shane,
I have found the reason of my problem but I don't know how to solve it:
if you use PlayForeground inside a function, it works the first time you
call that function but not the following, if you look the stderr.txt you
get:
Loading Sound Data. Specs:
Frequency: [44100]
Format: [AUDIO_U8]
Channels: []
Silence: [€]
Samples: [4096]
Size: [1129270338]

------------------------------------
Couldn't open audio: Audio device is already opened
------------------------------------
in the first call, which is good and audio play as expected, but in the
second call you get:
------------------------------------
Loading Sound Data. Specs:
Frequency: [1441791]
Format: [UNKNOWN]
Channels: [ ]
Silence: [ ]
Samples: [65535]

... which is obviously wrong for all audio parameters.
Closing the audio device before second call, probably solve the problem,
but I don' know how.
Any suggestion?
Best,
Giuseppe
