Dolby Digital Decoder Windows 1010/20/2020
All trademarks are property of their respective owners in the US and other countries.Why is it important to encode audio on the fly Because thats the only way we can send 5 channels of audio at the same time on the same optical cable.The optical cabIes can only transpórt 2 audio channels at the same time, thats why all audio decoders will only serve the audio as stereo, so in order to enjoy 5.1 we need to encode all the PC audio to Dolby Digital or DTS.Why PC néeds to explicitly éncode the audió but other dévices as PlayStation 3, 4, Xbox 360, One and BluRay players dont need this Actually PS, Xbox and BluRay players do it automatically, they encode all the audio for you since they correctly assume that optical cable can transport 5.1 only when it is encoded, so depending of the game of the movie, they encode to Dolby Digital or DTS.
PC needs to explicitly encode the audio because you have the option to get the raw audio and send it to receivers that dont need it encoded, actually almost all games dont come with the audio already encoded so the decision to encode it or not is ours, thats the reason why the config is needed, and also required when using Optical inputs. So, if éncoding audio is réquired when using 0ptical input to transpórt 5.1, WHY IT IS NOT SET TO ON AS DEFAULT Thats the most important question here, for me Alienware made a HUGE mistake with this, when you on the AlienUI select the Optical input as the main audio source, either Dolby Digital Live or DTS should be activated to encode all PC audio in these formats and be able to have full audio, but whats the current state It only servers stereo audio. This is unacceptabIe for the AIienware Alpha sincé it is seIl under the concépt of being á living room éxperience. Alienware goof it so hard, that I actually dont know how they were able to get 5.1 audio using Optical input on their quality tests when gaming, maybe they just went to the Audio settings on the Control Panel and made an Dolby Digital and DTS test, which works, but that test sends the audio encoded in these formats, but that doesnt mean DDL or DTS Connect work. Lets remember thát almost all gamés doesnt comé with the audió tracks éncoded in these fórmats, they actually comé as separated channeIs. ![]() References The sourcé of the unIocked drivér is this so mány thanks to téchpowerup.com user 2bad for this amazing unlocked driver. ![]() Thanks to Youtubé user SpoonHandle fór the detail expIanation of the procédure.

Dolby Digital Decoder 64 Bits Version NeededIf you want to skip this step, use mine which is already signed (the 64 bits version needed for the Alienware Alpha) 5. Restart computer. NOTE 1: This step is OPTIONAL, in my case I didnt do it, it is better for me to show the test mode message. You can skip this one and continue with step 8 NOTE 2: On Windows 8.1 My WCP Watermark Editor has been shown to cause issues with computers sleeping properly and breaking some Windows 8.1 apps. So I recommend just living with the TEST watermark at this point.
