WMVHD (Windows Media Video High Definition) files can contain a 5.1 channel audio stream. If you play such a file on a computer that only has two speakers then you will only hear the sound from two of the six channels. This causes for example the voices (center channel) to be almost unhearable. The solution is to downmix the six (5.1) channels into two channels. There are two ways to do this, you can either use AC3Filter or ffdshow. In ffdshow Audio decoder configuration, go to the Codecs page. Scroll down to the bottom of the list and set Uncompressed to All supported. Now go to the Mixer page and enable the checkbox in front of Mixer to activate the mixer filter, finally set the Output speakers configuration to 2/0 – stereo. In AC3Filter options, go to the System tab and enable the checkbox in front of PCM (Pulse Code Modulation). Also set the Output setting to 2/0 – stereo on the Main or Mixer tab.
