Hey guys, can someone recommend me a good sound card to use with my Sony HT-RT3 speakers so I can get Dolby Digital 5.1; using a single optical cable and running Windows 10
 
Solution
Pretty much. The soundcard is simply taking an uncompressed 5.1 stream and converting it to Dolby Digital via Dolby Digital Live, then sending that signal via optical to the speakers, which then converts the digital signal to analog.

If you want to run a test, you can play back an already existing Dolby Digital file, to make sure your speakers can play it back fine (if they're a 5.1 set using optical, I'm sure they can. A test never hurts though).
Assuming your motherboard doesn't support Optical Out/Dolby Digital Live encoding (if it does, just use that), the best overall option is the Creative Soundblaster Z. Just set output to Optical within the Creative app and enable 5.1/Dolby Digital Live and it should work.

Again: Check to see if your motherboard already supports this; many do.
 


Stereo is expected when using Optical if you aren't using Dolby Digital Live/DTS-Connect to convert audio to Dolby/DTS in realtime. Check to see if your motherboard supports either feature.
 


No. If you output via digital, then some other device is doing the conversion back to analog. In this case, your speakers. The quality of your soundcard at that point is moot; the only thing it's doing is transferring the audio stream to some other device to process.

So essentially the sound card's main use in this circumstance is to take the audio, convert it into a dolby digital signal and send it to my speakers which then accept the dolby digital signal and decode it into 5.1 audio ?

If that's the case I'm fine with it; I know digital audio isn't subject to quality changes due to the soundcard and all I need is the ability to output 5.1.

Though I do have a pair of 598s which would benefit

Okay thanks for the help; just ran a dolby trailer and the 5.1 works fine.

Main reason I want to setup the 5.1 is for games and entertainment so will look into getting a Sound Blaster Z, plus I've got a few pairs of decent headphones that I usually run via my walkman but never used on my pc due to not having adequate sound quality.

Thanks for the help
