Title: Playing Cds In 5.1?
Post by: constrictor on March 19, 2004, 09:00:00 AM

I have XBMC set to play MP3s and all files on my network or hard drive through all channels on my Dolby Digital receiver, however, when I play an audio CD through the Xbox drive, it only plays in stereo.

Is there a way to make the CD Audio play through all channels like MP3s do?

If you turn on DD/AC3 passthrough and 'output to all speakers' it will play to the rear speakers.  Not sure about the center channel since I don't have one.  Sounds pretty decent too.

Dunno, I use my amp to output to all 5 speakers.

btw the passthrough setting won't make any difference as CD audio is 44.1KHz and passthrough requires 48KHz.

Yeah but somehow my reciever still locks onto a Dolby Digital signal when playing mp3's.  I think it upsamples to DD5.1.

You need the "Advanced A/V" pack.  You should be able to find it at any Best Buy.  However be aware there are 2 A/V packs, one contains S-Video out, the other contains Component video out - they both contain a digital optical output.  Just make sure you're getting the right one for you tv.

Default output for digital is to encode to AC3. It'll be 2 channel unless you have output to all speakers on, then it'll be 5.1.

See, thats what I thought too....but as my original post said, if I play an MP3, it decodes into 5.1, but if I play a CD, it plays in 2 channel mode only.  I have the Advanced A/V pack using an optical cable.  I also have the setting to output to all channels turned on, yet CDs still only play in 2 channel.

Is this a bug?

I guess the CD code doesn't support multi-channel.
