SoundLatch

SoundLatch prevents Bluetooth speakers, soundbars, headphones, and USB audio devices from entering idle standby mode during quiet periods. It maintains a controlled audio stream using one of four modes—Digital Silence, Near-Silent Signal, Periodic Pulse, or custom Compatibility Mode—to ensure your hardware is ready when the next sound starts. The app features a compatibility wizard to test device timeouts, saved profiles for multiple devices, and a persistent notification for manual control.
