Any one playing this on the Mac with a HDMI adapter to a receiver? I am running it on an i7 MBP with a MonoPrice HDMI adapter to a Denon receiver and then to a monitor. While iTunes, YouTube, etc. play fine through it, when I tried the LOTRO Mac client, the sound was completely messed up from the intro movie throughout character creation. I just unplugged the adapter a stuck with the built-in speakers for now. While it is near impossible to diagnose HDMI issues, it would be nice if the client gave me the option to use the internal speakers instead.
