Having problem - ADA 890....

[Platypus]

ariel, I'm not sure I understand exactly what you're saying, but yes, the source will need to have an AC3 stream to be effective in the Dolby Digital mode. I think the soundcard configuration would be the same regardless of whether you play a DVD, or other AC3 enabled source, that is, in Creative Control Centre, disable the "decode AC3 and Dolby Digital" option.

For instance if you have an .AVI with an AC3 stream, whatever player you are using may need an AC3 plug-in, and should be set to AC3 passthrough mode. However a topic here:

has someone with the same problem, and suggestion is maybe try different players.

Just as an FYI:

Installation Manual for your Altec Lansing ADA 890 speakers

Creative Labs Downloads Select Sound Blaster, then 24-bit Advanced, then your correct model number. If you then Select Application, you will find an update (11 Feb 2003) for Creative Speaker Settings version 1.00.56 SPKS-WEBUP-2-LB

New Features or Enhancements
-Option to synchronize settings in Creative Speaker Settings with Microsoft® Windows® Control Panel speaker setup settings.
-More intuitive Speaker channel test; sequence now moves in a clockwise direction.

Fixes
-Correct functionality of Creative Speaker Settings when the sound device in the Windows control panel is changed.

Hope this helps out.
