I just put together a new PC with MC 12 and am familiar with MC 11 from previous installs. I am trying to use the Realtek 7.1 HD sound built into the motherboard...however, I have been unsuccessful at getting any sound from MC 12 out anything other than the L/R output. It shows 3 zones available to me in MC 12, L/R, C/Sub, and RS/LS. I created 3 two channel zones and can only get sound from L/R and not the other two. I have also tried Direct and Wave settings. Can someone please help point me in the right direction, I'm sure there is a setting or two I am missing. Also, the Realtek Manager is set up for 5.1 audio. Thanks in advance.
