Git commit e3526dc7c5ec3f7c18ca67dddfb73f611186d460 by Ismael Asensio. Committed on 05/02/2024 at 18:50. Pushed by iasensio into branch 'master'. kcms/soundtheme: Improve error message for sound not found This error is the most common a user can experience in the KCM, as it will happen if a theme doesn't provide one of the preview sounds (ex. 'freedesktop' and sound 'batery-caution') To minimize possible confusion for users (and bug reports), offer a more clear and translated string on why it's happening, and show it as an information message rather than an error.
