pygame: Unable to open sound as Sound object, but able to play as music?

Question

The following works as expected:

pygame.mixer.init(frequency=22050, size=8, channels=2, buffer=2)
pygame.init()
pygame.mixer.music.load('audio/beep.xm')
loop_event = pygame.USEREVENT + 1
pygame.mixer.music.set_endevent(loop_event)
pygame.mixer.music.play(loops=-1, start=00)

However this:

pygame.mixer.init(frequency=22050, size=8, channels=2, buffer=2)
pygame.init()
beep = pygame.mixer.Sound('audio/beep.xm')
beep.play()

Gives the following error:

pygame.error: Unable to open file 'audio/beep.xm'

I can't see any related issue to this as I am sure I am initialising pygame.mixer correctly and as it works as music it doesn't appear to be an issue with the fule itself. I have tried using the full path and variations of the path, all gave me the same error.

Answer 1

The Pygame Docs for pygame.mixer.Sound state:

The Sound can be loaded from an OGG audio file or from an uncompressed WAV

xm audio files are not supported by pygame.
