I'm at the end of building out a 16 ch 9.2.6 basement theater. I'm setting up either an HTP-1 or JBL SDP-55 to run things. I'm also in the middle of building a multipurpose PC that I want to connect to these that can fully utilize the Atmos setup I have. My chosen motherboard (Asus Maximus xii Extreme) has no HDMI out, and I plan to use my video card HDMI ports to run a multi monitor setup where I plan to max out the resolution and performance with video only, so I won't have any ports nor GPU processing bandwidth I care to allocate to audio. Instead, I want a separate audio solution altogether. I'm not yet convinced that an internal sound card will be best due to internal interference, but I'm open to suggestions on either internal or external options that can get me a nice bitstream to my AVR that has the bandwidth necessary to carry Atmos. I'm not sure that I really need a DAC since I plan to let my AVR do the decoding, but if there are suggestions on DACs that are better than what I'm already planning then I'm open. Please let me know if there are some suggested paths where I can start some research on this. Thanks!
