Audio devices do not all report playback in the same way.

Some drivers provide useful timing information. Others report estimates, buffered positions or values affected by additional layers between the game and the speakers. That makes audio timing more complicated than simply asking the sound device where the music is.

Older parts of the engine relied heavily on those reports. That worked well enough on many systems, but it also meant that differences between drivers could affect how the engine understood playback.

SereneAudio handles this more carefully.

Rather than assuming that every backend provides the same quality of information, the new system checks how audio is being submitted and played across each supported output path. This allows us to account for differences between modern callback drivers, older polling systems and compatibility backends without allowing one unreliable report to disturb the rest of the engine.

Recent testing exposed an underrun in one of the older paths. The problem was not simply a buffer that was too small. The backend was being fed using behaviour inherited from the previous audio system, which no longer matched the way SereneAudio operates.

We corrected the feed path rather than hiding the fault behind a larger buffer and more latency.

StillRiver was used throughout the testing to confirm that audio remained stable, that the device was receiving data at the expected rate, and that the change had not introduced clipping or unnecessary delay.

For players, the result should be straightforward, audio should start reliably, remain stable, and behave consistently across different devices and operating systems. Keysounds should play cleanly, and older compatibility routes should continue working without holding newer hardware back.

SereneAudio gives us a clearer and more dependable way to handle those differences.

The complicated details stay inside the engine, where they belong.
