Thanks Adam. That worked on Windows, but now that I have switched 
to Linux Mint it is throwing this:
arsd.simpleaudio.AlsaException at arsd/simpleaudio.d(1170): params 
init: Operation not permitted
----------------
??:? arsd.simpleaudio.snd_pcm_t* 
arsd.simpleaudio.openAlsaPcm(arsd.simpleaudio.snd_pcm_stream_t) 
[0x55eab05a0f4a]
??:? ref arsd.simpleaudio.AudioOutput 
arsd.simpleaudio.AudioOutput.__ctor(int) [0x55eab059f7ec]

What should I do?
