I have a 2011 macbook pro with a thunderbolt/hdmi adapter connected to a receiver, so I can watch movies on my tv. Video files with 5.1 dolby have always played fine through this exact setup, however, recently, only 2 channel pcm audio goes through and is recognized on the receiver.
I know that the adapter is good, and it isn't the receiver because I have tried other devices on the same ports. So it must be something on the macbook end.
8 channel is selected under hdmi in midi options, and hdmi is always selected as output in the movie player I use. There is no reason it should still only be 2 channel on my receiver.
I have tried 3 different hdmi cables and 2 different thunderbolt to hdmi adapters. All the same. Also, all the hdmi ports on my receiver have dolby with other devices (such as my ps3, cable, etc) SO I can rule out the receiver and the cables...it has to be my macbook.
I am dying to find an answer to this...asked the question multiple times in the apple community with not even one response...please help if you have any ideas!
Thank you
PS. I am on 10.7.4 using an Onkyo HT-R590 receiver. I currently have 2 different adapters that I know both work.
