In this particular case, these audio issues can be traced back to a newish feature in Windows 10, known as hardware-accelerated audio. While in principal hardware acceleration of audio and video can result in far-better performance than software-accelerated audio/video playback, if not perfectly implemented it can cause some severe problems and side effects. The aforementioned audio glitches and delays in audio playback that affect Windows 10 systems are completely a result of the drivers. Unfortunately, poor drivers have long plagued audio devices on Windows and while we are finally at a point where most PCs and laptops will play audio out-of-the-box without needing to install 3rd party drivers, oftentimes these WHQL-certified audio drivers are still not up to par and have considerable issues.

Garbling of the first ~half second of audio output after a period of silence.

This can be easily verified by clicking on the audio icon in the taskbar and changing the volume level: if it takes longer than 100ms for the audio notification previewing the volume level to sound, you are probably affected by this problem. A great example of this is the Windows 10 UAC prompt, where the message box can appear but the accompanying ding does not play until a full second or so later.

After a period of silence, it takes up to one or two seconds for audio to begin playing.

There are a number of symptoms, but the most common and annoying audio problems that can be resolved with this guide are: This problem can occur with different hardware, but many reports of these issues have been reported with Realtek audio chips. This guide features a number of common issues faced when playing audio in Windows 10 and a possible solution. A common problem that faces some users of Windows 10 is delays in the audio output. While Windows 10 brings many considerable improvements to audio and video features and performance, it also appears to have its share of bugs and idiosyncrasies.
