OK, there's a number of possibilities. Let's go down the line...
1. SACDs and DVD-As only play in full resolution/multichannel (when available) over the 6 analog outputs on the player. You must have those hooked up to the inputs on your receiver to hear SACDs and DVD-As in their full glory.
2. Some SACDs are 2 or 3 channel only.
3. SACDs will not output the multichannel audio over the digital connection. See #1.
4. Therefore, you must switch to the multichannel input on your receiver and not use the DVD or CD inputs.
5. Sometimes, you may have to tell the player itself to output to the multichannel outputs instead of using the standard CD layer of the SACD. Players should be smart enough to do this themselves, but some aren't.
And people wonder why DVD-As and SACDs didn't catch on...
Did I miss anything guys?
