Class Driver
AC3 Test
(System)
6/30/2025 84
Erratum
The HD Audio class driver hdaudio.sys exposes AC-3 data
ranges on S/PDIF Kernel Streaming pins incorrectly.<br
xmlns="http://www.w3.org/1999/xhtml" /><br
xmlns="http://www.w3.org/1999/xhtml" /> The
compressed AC-3 transport is "stereo", "16-bit", and at the
same sample rate as the uncompressed format. As such,
AC-3 data ranges are expected to have MaximumChannels
= 2, and MinimumBitDepth = MaximumBitDepth = 16.<br
xmlns="http://www.w3.org/1999/xhtml" /><br
xmlns="http://www.w3.org/1999/xhtml" /> However, the
HD Audio class driver sometimes incorrectly exposes a
MaximumBitDepth of 24 or even 32.
