Emulator

What's the problem?

When I pick a song, and begin the dance, the sound is incorrect as the soundtrack plays normally but unfortunately is intertwined with a strange noise which loops infinitely.

Dolphin version with the problem (as it appears in the title bar, Ex.: "R
4779" or "R 6403M"):

Dolphin r6515 (32 bit)

Operating system and version:
Windows 7 32 bit

Game ID (as it appears in game properties, Ex.: "GZ2P01" or "RSBE01"):
SMOP41

Was the ISO a plain dump from disc, compressed and/or scrubbed?
Plain dump from disc.

Please provide any additional information below.

Game runs at full speed (100%). No slowdowns. Tested in OpenGL, DX9 and DX11 modes.
All audio options are enabled. Tried enabling and disabling "Enable audio throttle" but no difference. Tested all available audio backends (XAudio, DSound and OpenAL).
