+## [1.0.14] – 2026-03-17
+### Bugfix
+Audio device handling has been completely reworked to account for dynamically assigned addresses of USB audio devices
+This prevents incorrect device mapping after reboot or reconnection
+### Added
+Introduced a new settings parameter to control ALSA card output volume

 ## [1.0.13] – 2026-03-15
 ### Bugfix
 - Fixed an issue where audio device addresses could change on each boot.
