You should see a white icon in your system tray (right-bottom of your screen). That is Haali Media Splitter. Right-click on that icon to switch between the audio tracks that available within the file.

You should see a white icon in your system tray (right-bottom of your screen). That is Haali Media Splitter. Double-click on that icon to view its options. You can also get to the options by clicking on the Haali Media Splitter shortcut in the start menu.

Once you are in the Options screen, click on 'Languages'. There you can set the preferred language(s) for audio and subtitles. The language should be input using a three character code, for example eng for English. A list of codes for each language can be found here. The language code should be input as lowercase, so 'eng' is correct and 'ENG' is incorrect.

There is no way to select a specific audio track during playback in Media Center (at least not without using third party plugins). It is only possible to pre-configure which one to use. By default the first one is used.

See above for instructions on how to configure the preferred language for audio streams in Haali Media Splitter.

Yes. That is possible.

If ffdshow is causing an incompatibility problem with an application or a game, then you should blacklist that application in ffdshow. First you need to find out the filename of the main executable of the application. For example "oblivion.exe". Now go to ffdshow video decoder configuration. Click on "DirectShow Control". Enable the box in front of "Don't use ffdshow in:". Then click on the Edit button behind it. Add the filename of your application to the list and then click on OK.

You can do the same thing in ffdshow audio decoder configuration.

The Codec Tweak Tool has an option to export (= backup) and import (= restore) settings.

Most receivers are able to decode AC3 and DTS audio. If you have connected your receiver to your PC with a digital cable, then you can send AC3 and DTS audio directly to your receiver by using S/PDIF pass-through.

It is also possible to output other audio formats to your receiver by re-encoding the audio to AC3 in realtime.

The location of the S/PDIF options depends on which decoder that you are using, either ffdshow or AC3Filter. The codec pack uses ffdshow by default.

ffdshow

In ffdshow audio decoder configuration, go to the "Output" page. There you can find checkboxes to enable S/PDIF pass-through for AC3 and DTS audio.

If you also want to send the audio from other audio formats to your receiver, then you need to enable the "AC3 (S/PDIF encode mode)" checkbox under "Supported output sample formats".

Only the audio that is processed by ffdshow will get re-encoded to AC3. If you also want ffdshow to process audio that has been decoded by a different DirectShow filter, then you need to go to the "Codecs" page in ffdshow configuration and set "Uncompressed" to "All supported".

AC3Filter

To activate S/PDIF output, enable the checkbox called "Use SPDIF" that is located on the "Main" tab.

All S/PDIF options in AC3Filter are located on the "SPDIF" tab.

If you want AC3Filter to process audio that was decoded by a different DirectShow filter, then you need to enable PCM on the "System" tab.
