From bb132ceeaf861c4a8c78f665bfbd9046d50a7ffb Mon Sep 17 00:00:00 2001 From: NeilClack Date: Sat, 11 Jul 2026 11:39:58 -0500 Subject: [PATCH] fix: resolve 4 critical audio mixer bugs (v0.5) - SwitchDevice volume silently zeroed: Init uses cfg.SavedVolume, SwitchDevice restores saved volume after reopening device - SwitchDevice not persisted to database: caller saves SelectedAudioDevice - Device restore passes invalid 'system default' to SDL: now passes '' - Stop() no-op when audio toggled off: removed AudioEnabled guard Regression tests added for all 4 bugs.
