I'm new to this forum, but not new to audio/video.
Here's my setup, (XBox 360, Verizon Fios, Mac Mini, Blu-Ray player) HDMI --> Denon 1911 --> TV (HP 42 inch LED LCD)
All 4 are connected by HDMI to the receiver, then HDMI to the TV.
Have 5.1 set-up with Polk speakers with left, right, center, left and right surround and sub.
On all in-puts Fios, Blu-Ray, and XBox, all the channels are working. When selecting my Mac Mini (late 2012 version, 2.6 GHz i7 processor running 10.8.4, 8 GB ram, with the Intel HD 4000 with 768 MB graphics card), only the right channel is playing.
I use the computer to play movies that I have stored on my hard drive, pandora, and iTunes.
I have gone through all the setting that I know of in the Denon and in the Mac System Preferences...I'm a little bit unsure of where to go to try to rectify this.
Any thoughts are greatly appreciated and welcome. I had this setup in a previous house and then moved. Not sure what changed from then until now.
Thanks in advance for any help. Let me know if you need more information about anything and I'll do my best to provide an answer.
