Alienware didn’t notice that none of the drivers allow us to encode to Dolby Digital or DTS, so after digging around the web I found some people with the same problem (not from Alpha, not even on Alienware, people with RealTek sound cards) that were able to modify the driver to be able to encode the audio (for cards that have the needed hardware to do it, lucky us the Alpha’s card can do it).

After reinstall several versions of the driver, I found that only the Audio Manager packed on version R2.71 works fine, not even R2.78 which is the latest one or the one Alienware gives us as default (which I don’t know the number, probably R2.78).

My Realtek Audio Manager DIDN’T WORK AT ALL, so it was really hard for me to start the troubleshooting of the issue, not sure if other users have the same problem but the speaker icon on the tray was not displayed and when I tried to manually start the program, nothing happened, not even a log file with details of the error.

So to summarize this, I detected 3 big problems: Let's remember that almost all games doesn’t come with the audio tracks encoded in these formats, they actually come as separated channels. This is unacceptable for the Alienware Alpha since it is sell under the concept of being a living room experience.Īlienware goof it so hard, that I actually don’t 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 doesn’t mean DDL or DTS Connect work.

That’s 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 what’s the current state? It only servers stereo audio. So, if encoding audio is required when using Optical input to transport 5.1, WHY IT IS NOT SET TO ON AS DEFAULT? PC needs to explicitly encode the audio because you have the option to get the raw audio and send it to receivers that don’t need it encoded, actually almost all games don’t come with the audio already encoded so the decision to encode it or not is ours, that’s the reason why the config is needed, and also required when using Optical inputs. Why PC needs to explicitly encode the audio but other devices as PlayStation 3, 4, Xbox 360, One and BluRay players don’t need this?Īctually 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.

The optical cables can only transport 2 audio channels at the same time, that’s 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 is it important to encode audio on the fly?īecause that’s the only way we can send 5 channels of audio at the same time on the same optical cable. I recently got an Alienware Alpha, I’m pretty happy with it except for a big issue with the Optical input and its driver’s ability to encode sound using Dolby Digital Live (DDL) or DTS Connect on the fly.
