Digital Decoder
« on: September 15, 2004, 01:00:00 PM »
Think this is in the right place, sorry if it's not!

Got a new computer with Creative Audigy 2 NX and Creative Inspire T7900.  Hooked up to my computer...works like a dream (OT).  I used the X2VGA+ to hook my XBOX up to the monitor and that works fine!Set the audio options to Dolby Digital (No DTS as i knew the audigy didn't support it).  But i got sound on the dashboard only, not in any games :(

Browsed through some of Creative related forums and found that i would need a decoder as my Audigy DOES NOT have one built in :grr: Found the best decoder i could here

What i want to know is if there is any software in "the usual places" to decode the digital audio signal before it is transmitted through the digital cable to my Audigy?

cheers

The reason the dash plays audio through is because it is PCM (2 channel), while the games are AC-3 (Dolby Digital 5.1 channel). You can switch off the Dolby Digital in the dash and just put it to stereo, and it will play PCM audio for both games and dash, but that won't take advantage of your new 7.1 channel system!

Your sound card should be able to decode the AC-3 signal coming through the optical and output it through the analog outputs on the sound card. The sound card must have a decoder built in, otherwise you wouldn't have Dolby Digital 5.1 sound when you play back a DVD on the computer.

What it means to decode is to convert it from digital to analog, like that decoder box you linked to does. You plug one digital cable in, six analog cables come out (one for each channel, or speaker) which connect to an external amp (the T7900 system).
