Playback is implemented using a target-specific PCM layer, using the STM32H7 SAI & DMA registers directly. There are a number of pop/click issues: 1. Slight click when powering up the amplifiers 2. Click when starting and stopping playback 3. Popping when changing playback frequency 4. Popping when shutting down It should be possible to eliminate or at least mitigate (2) to (4) in software, but (1) happens as a result of powering on the amplifiers while everything is muted so might be unavoidable.
