Update January 15th

On January 15th, an update was made that includes a few adjustments to the sound mode.

What's changed?

Colors for player buttons
The player buttons for sound mode were previously always black with a transparent background.
This has been changed so that they now have the same colors as the buttons for Menu, Bookmark and Text mode.

Supporting sounds could be started multiple times
A fix has been made so that the sound cannot be started again until it has finished playing.
