 - The sound card's volume level might be set too low. Snes9x doesn't alter the
   card's master volume level so you might need to adjust it using the sound
   card's mixer/volume controls usually available from the task bar or start
   menu.

+- If experiencing crackling, try the following in the Sound Settings dialog:
+    * Ensure the "Synchronize with sound core" option is enabled.
+    * Increase the buffer size.
+    * Switch the sound driver from WaveOut to XAudio2 or vice-versa.

+    * Enable the "Dynamic Rate Control" option.
+    * Change the "Playback Rate" to 48000Hz. Versions of Windows since Vista
+      have included a sound server that controls audio. It usually runs at
