Enable Extended Window Media Audio support (Speaker Configuration)
When enabled, Windows Media 9 content will be allowed to play at 24bit/192khz (if the media actually contains such quality). This setting also enables any other Audio Related Setting on this page.

Use AC3Filter as a post-processor for DRM Encoded Windows Media Streams
When playing DRM encoded WMV files, Zoom Player WMV Professional allows you use AC3 Filter as an audio Post-Processor (can be used to convert Windows Media Audio to AC3 for S/PDIF output). This requires AC3 Filter v1.01RC5 or newer and the AC3 Filter must be specified to accept PCM connections.

Use Windows Media Audio over S/PDIF (Requires a WMA compatible receiver)
When enabled, Zoom Player will instruct the Windows Media Audio decoder to pass its audio data through S/PDIF to an external receiver. Please note that this requires an external receiver capable of decoding WMA content.

Speaker Configuration
This toggle determines how the Audio Channels are mapped when multi-channel audio is encountered. Notice that the "Direct Out" value means that the audio is output as-is without any channel downsampling (do not confuse this with S/PDIF!).

DRM Color Space Connect
When playing DRM encoded WMV files, Zoom Player WMV Professional allows you to specify the type of connection between the WMV decoder and the Video Renderer.

Only use this interface if you are experiencing problems.
