BGM or Sounds are robotic?!
Since PCSX2 0.9.2 ADMA audio has been implemented, which allows many games to output FMV audio and many of the previously missing sounds/BGM, however this has only just been implemented and has bugs, leading to many games sound somewhat ‘robotic’, there is nothing that you the end user can do to fix this, the developers hope to have this resolved in the future.
