Multichannel over HDMI: "could not be started on WASAPI using '96kHz 24 bit 6ch'

I have reinstalled the RealTek audio drivers/codecs from here http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=24&PFid=24&Level=4&Conn=3&DownTypeID=3&GetDown=false more times than I care to remember.

Exactly. I also have Realtek HD Audio Manager
JJJ:
Hi BD. Yes I have that in Control Panel also. It allows one to implement various effects for the available devices - in my case only for 2-channels. But all the Realtek options in Sound (right click on the volume button and select Playback Options) relate to jacks other than HDMI. There should be a device called Realtek HDMI Output. It seems to be a popular problem but be damned if any of the proposed solutions have worked for me. I did have a device called Intel HSR5 Display Audio. This was connected to the HDMI jack but was restricted to 2 channels. I could not see how to change the number of channels. I could play stereo tracks over HDMI with this. However, I disabled this to see if it was "obstructing" Realtek access to the HDMI jack. No joy. (And I can't figure out how to re-enable it!) This is driving me nuts.

BD you (and possibly others) may find this useful. I contacted the reviewer I referred to above. Very kindly, Andrew responded straight away and this is what he said:
"Realtek has nothing to do with the HDMI audio on this board. You don't even need to install the drivers unless you plan to use the line-outs (I don't).
First, make sure that you have the latest GPU (the HDMI audio drivers are included in it) and the Management Engine (MEI) drivers installed.
Second, open the audio control panel and "Configure" the device to match your speaker setup.
Third, HDMI is driven off of the EDID so most likely this is the problem (assuming that you already had step 1 completed). Troubleshooting EDID issues can be problematic, but there are tools for the PC and CI market that make it possible. Personally I use a HDMI Detective to ensure that the the EDID is always broadcast to the PC (this keeps the TV's EDID from resetting the audio config on the PC). If the AVR isn't presenting its capabilities properly, using an HDMI Detective will fix it."
I will check his points 1 and 2 but I've also sent a note to John at Theta.

I was not successful when I tried. I hoped you might have success. During my experimentation, a long, 35 foot HDMI cable damaged the HDMI output, from it's weight, of my PC. It was a blessing in disguise. After that I purchased a Radeon 7750. The AMD GPU works flawlessly and supports a wider variety of sample rates. It does show the audio device to which it's connected for the most part but not with Theta. I don't think this is really a "Theta" problem but they should be notified as many will be using HTPCs. My Casablanca is non-HD and the devices I am trying with the same results as yourself are all non-Theta but have HDMI. The AMD Radeon GPU works fine with the Casablanca HD for all popular sampling rates with the two people I have gotten to try it.
