Anyone know anything about this? thanks.
In my experience, the latency is when you use certain soundcards to encode into Dolby Digital Live. For example, if I use my SB Z soundcard to encode into Dolby Digital Live (instead of just using it's own SBX Pro surround) then I get a bit of latency when that DD 5.1 signal reaches my DSS.
The mixamp itself, for whatever reason, doesn't have this latency on consoles. Perhaps they are faster at encoding Dolby Digital Live at a more hardware-level Vs. certain soundcards. Since I assume you're trying to use it with PC though, it's possible your computer is creating some latency when trying to first to encode a DD 5.1 signal for the mixamp.
I haven't heard any complaints about Dolby Headphone soundcards like the Xonar U3 or Xonar DGX though.
