I also tried realtek’s “ATI HDMI driver”, but it didn’t output sound when specifically selected in mpc’s Output box (makes stereo sound if System Default is chosen but silence if not). I’m using ATI’s latest 9.12 HDMI audio driver… More info… this ati 5750 has audio built in to it using a realtek chipset. Ideas? Maybe this ATI HDMI port is not spdif, so your turorial doesn’t apply? I have no idea here… It’s also worked for HDMI from the Tivo before. – my receiver says PCM L/R (stereo), even though I see 6 ch in all software… My receiver is set to surround decode, a setting that works for all my optical connections (i.e. I’m assuming because the ATI 5750 HDMI port is not spdif? Ok… now what. and it does not say “passthrough” in output. I see all 6 ch in the AC3Filter making sounds in their bargraphs. The AC3 Filter icon appears in the system tray. mpeg video decoded from by tivo, it plays with AC3 6 ch. (But wouldn’t this harm a lot of formats?) everything? or just the DTS and AC3 stuff only?… I have only unchecked the AC3 and DTS stuff in Internal Filters… on both sides (Source Filters and Transform Filters)… If you mean for us to actually uncheck all, please clarify. – when you said “uncheck everything in filter settings” do you mean in Internal Filters? and really. I have an ATI 5750 card, and I followed your MPC-HC instructions. Please give feedback if everything worked, or if you encounter any problems. If the only way to control volume level is by using your reciever, then it should be working. Press OK to save and start Mediaportal to test.

Set Audio decoder to AC3Filter and renderer to ATI HD Audio rear ouput.Ĭontinue to the Movie Post Processing section and add AC3Filter by double clicking it in the lower pane, make sure the selection box is marked.
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.
