5.1 finally transmitted optically possible

Now have the device connected via optical port and tested via an A / V receiver (Pioneer VSX-C502) to a 5.1 system. First of all: 5.1 sound to work properly, ie to "lynnemusic" (just google, links are not allowed here!) The test files are accurately reproduced.
To do so:
1. Uninstall all previously existing codec packs and audio filters in the Windows Control Panel.
2. K-Lite Mega Codec Pack (see Google) download, select at installation only profile "Lots of Stuff".
3. Connect the sound card via USB to PC and visually A / V.
4. Bundled CD install (completely). Best also make the Creative update. Restart PC.
5. In Windows Vista / 7: Right-click on Windows Audio Devices icon - click> SPDIF out and click "Make Default" -> Playback Devices. SPDIF Out click again and select "Properties". Select In "Supported formats" everything. Select sampling rate depending on the A / V. Go to the "Advanced" tab. Here select "Dolby Digital Live".
6. Reiter "Sound Blaster" now choose. On the "Settings" button. "Audio Control Panel" window opens. Reiter "speaker" -> 5.1 speakers. Select the tab "Encoder". Here's a hook in need "Dolby Digital Enable Live" to be set. Close Audio Control Panel.
7. Go In the window "Properties of SPDIF Out" to "Advanced" tab, here you have after you click the "Test" will be heard a stereo test tone.
8. If everything works so far as (If you have problems: Possibly A / V Receiver boot, select correct source there / Dolby Pro Logic etc on A / V deactivate, see also the comments on the customer review of the device by the user gesus "moe") must Now any Surround files can be played properly. If not with the Windows Media Player, then with the Media Player Classic (Home Cinema) installed in step 2! More AC3 / SPDIF filter settings etc are so much goodness NOT required!
9. Have fun with the unit!

Explanation: Opt in Windows as a sound card "Speaker" (Sound Blaster X-Fi Surround 5.1 Pro) rather than "SPDIF Out" (Sound Blaster X-Fi Surround 5.1 Pro), so in optical connection shows the A / V, that he "Analog Stereo" receives. In contrast, when "SPDIF Out" indicates the AV that it was "Digital 5.1 sound" to. The "speaker" (Sound Blaster X-Fi Surround 5.1 Pro) is therefore recommended only when you connect the analog soundcard and non-optically to its speaker / AV!
Furthermore allows precisely the activation of Dolby Digital Live that in optical connection of digital audio stream is transported in Dolby Digital Live Format (see also above customer review or Wikipedia) - and thus makes "real" undistorted digital 5.1 sound enjoyment possible.

Update: Copies you best equal to a PC or the supplied CD makes you a backup of it elsewhere. Without CD can namely Dolby Digital Live is not installed and must also do without Audio Control Panel - there are on the Creative website that is only a beta driver for download and no software (lousy support).
