    I've been using an optical cable from my macbook (2009) to play files (mkv, avi, mp4) with Dolby Digital or DTS encoding with no problems for a long time.

     

    Until today.

     

    Now, every time I start one of these files, my output device in the sound prefs panel switches automatically from "Optical Digital-Out Port" to whatver else is avaialble. I've actually gone as far as removing ALL other options except airplay, which I can't delete since that is my receiver, but if the file has encoded output, it just outputs silence since it switches output devices. If I change the output device in VLC to "Built in output" then it plays, but it just uses Pro Logic. I had no troubles with this until today. I just don't get it. I changed nothing.

    I tried restoring a Time Machine Backup to the day before this problem started and it worked insofar as I am now hearing sound when the encoding is DTS or Dolby Digital. Oddly, the sound device selection still is jumping to something other than Digital Out...for example, it jumps to "soundflower" but still works.

    Hi, I have a Sony STR-K1500 A/V Receiver that has 2HDMI in and 1HDMI out, and a Panasonic LCD, I want to connect to my Mid 2012 MacBook Pro to both my Tv and receiver so i can get true 5.1 surround sound when I watch a movie that has 5.1 sound. I've been searching, and I found that this receiver doesn't handle audio via HDMI. So how do I have to make the connections to my laptop, receiver and tv? Do I have to connect the MacBook Pro to the receiver via hdmi and toslik, and then my Tv to the hdmi out of the receiver? I don't know waht to do, please help me!

    Per original post,

    First step is done.

    But i could not see any other device than built-in when I check preferences>sound>output.

    How can i fix it?

    Dear Parker,

     

    I will apologize in advance as I am not tech savvy as most of the people here. I currently have the imac 27 inch (late 2012) version. I just ordered a logitech z906 5.1 speakers. I'm a very simple person...just want to listen to music, watch movies online, tv shows online, and etc. through my speakers.

     

    I do not video edit, hook up through dvd player and what not. As such, all i want to know is...what cable do i need to enjoy true 5.1 surround sound through my imac? Is it (1) Thunderbolt to HDMI or (2) 3.5 jack and optical cable or (3) BOTH!

     

    Sorry fo the confusion and I'm just starting get familiar with all these technical terms. Also, i read all the previous post...where AUDIO MIDI all the other sections are grayed out besides stereo...what is the purpose of testing all the individual speakers when you mentioned that through 3.5 jack and opitcal, although it shows stereo, it will produce surround sound?

     

    Thakns again and look forward to everyone's input.

    I have a 2011 Macbook Pro and im using a thunderbolt/displayport to hdmi cable

    You have to choose 44.100hz and 2 channel 16bit audio in Audio Midi setup to get full srrround support.

    And what if, like me, you don't have an HDMI port and both your mini display ports (thunderbolt ports) are taken up by displays? I am fully aware you can have a 3.5mm optical adapter and use that however then when you change the settings in the Audio MIDI Setup to Encoded Digital Audio it jumps to another output device. Why is this and how do I stop it?

     

    Thanks, Jacob.

    I have exactly the same issue. Although I already have the optical cable and audio jack adapter by problem is as described previously.
