Elimination of clicking noise

The new firmware update makes the board more robust against SD cards with less performance.
Previously, when using a slow SD card, it could happen that there is a slight clicking noise when the hum loops. This is now fixed, effectively eliminating the clicking noise. As another effect of the increased robustness against SD cards with less performance, also any other sound transition has been further smoothened.

Fix ignition speed and retraction speed

Previously, it could happen that the change of the ignition speed and retraction speed of sound fonts different from the currently active one was not saved. This is fixed now.

Fix randomized boot sounds

With the previous firmware update, it could happen that the boot sound was not chosen randomly under certain circumstances. This is fixed by the new firmware update.

Minor bug fixes

The new firmware update fixes a series of minor bugs, enhancing the reliability and stability. These refinements, though subtle, contribute significantly to a smooth and consistent operation, ensuring an overall improved user experience.
