The custom Android firmware layer (often referred to generically as "KSW") has a messy, fragmented architecture. The MCU and Android frequently fail to synchronize state changes, dropping or misrouting audio packets. The Three Common Audio Bugs
The tool was created to address a chronic audio bug in KSW units where the sound output from the Microcontroller Unit (MCU) fails to initialize properly unless a preinstalled media app is launched first . ksw sound restorer 2021
