Recently, I modded my iPod to replace the clicker speaker with a Taptic Engine. I noticed that the vibrations are far less noticeable in Rockbox than they are in the stock firmware. Rockbox therefore seems to handle the clicker speaker differently than the stock OS. I wanted to ask how to change the frequency of said speaker. The Taptic Engine has a resonating frequency of around 50hz, which I would like for maximum haptic feedback.
Any help is appreciated!
