When installed, open Mediaportal Setup and go to Movie Player settings (see screenshot below). It uses Directshow for media processing and can therefore be used together with AC3Filter. Mediaportal is an open source media center software for windows. If the volume control doesn’t work and the only way to adjust the volume is on the receiver, then everything is working perfectly. This can be done by clicking the AC3Filter icon in the system tray when the movie is playing and see if it says “Passthrough” under “Output format”.Īnother way to test this is by adjusting the windows volume. You should now try playing back a video with AC3 or DTS sound to see if you hear anything, if there is sound playing you should check if digital pass-through is working. Then continue to the System tab and make sure it matches the following screenshot. Set “Output format” to something that matches your speaker configuration and is compatible with your receiver.Ĭontinue to the SPDIF tab, and make sure the settings under SPDIF passthrough match the following screenshot. Locate the AC3Filter config in the start menu under Programs. You can now close Media Player Classic Home Cinema. Go to Filter Settings and make sure everything there is unchecked, then continue to Audio Switcher and disable the built in audio switcher.Ĭontinue to external filters, choose Add Filter and select AC3Filter, press OK and make sure it is set to prefer. Important: Under “DirectShow Audio” make sure the right output is selected (not system default), in my case this is “ATI HD rear output”. Open MPC-HC, go to View > Options and select Output.

Combined Community Codec Pack (latest version includes MPC-HC)Īfter installing AC3filter and the correct drivers.

My specifications (when writing this tutorial):

Directshow capable media player, such as MPC-HC and Media Portal which will be used in this tutorial.

The correct ATi HDMI Audio Driver (not Realtek ones) – Link:.

ATi Radeon card with hdmi out (usually a DVI+sound to HDMI adapter).

Other configurations might work with these instructions, but I can not guarantee this.

It should be noted that this guide is intended for Windows XP running an ATi card with HDMI out.
