In recent days, Microsoft has announced two new experimental measures for assess the quality of audio drivers e video of Windows 10 and Windows 11. The ultimate goal is to ensure more stable and performing drivers for users, and reduce the number of crashes. The new measures are currently being tested: the company intends to collect feedback between now and February 21, and (also) on the basis of it will decide whether to keep them or not.
As for the graphics, the new measures focus in particular on playback of copyrighted content. The system will observe if the operating system experiences Catalog Reload events while loading files into mfpmp.exe. This may cause timeout errors from Netflix and other streaming content providers that protect their assets with Software Digital Rights Management (SWDRM). For a driver to pass Microsoft’s compatibility test, more than 99% of the devices it is tested on (the pool must be at least 200) must cause zero Catalog Reload when playing video in a day.
As far as audio is concerned, however, the test method will focus on the APO crash events (Audio Processing Object). When these occur 10 times in a row, the Audio service disables them to prevent further problems, but this may mislead the driver reliability test. Then you’ll check for APO muting cases in the last seven days and report the time the device has been playing audio. To pass successfully, less than 0.1% of devices must have experienced an APO disable.
