Disable audio output to DisplayPort device












29















I'm on OSX 10.9.2 using a Samsung SA850 Display connected to the display port of my MBP 15" Late 2012 Model.



All seems fine, but there is a problem with audio. Generally, whenever the display goes to sleep and wakes up again, my audio stops working. I found out that this is because the display has an integrated audio device, so for some reason this seems to mess with my system settings. I have no idea why.



This is kind of a clueless approach, but perhaps anyone knows how I can just totally stop OSX from even considering my display as an audio output device?

    See if the display port shows up in Sound properties "playback" tab, if it does, disable any display port entries in there.

Make the sound icon visible in the menu bar (at the bottom of the Sound system preferences window), then hold Alt ⌥ and click it to view all possible outputs. Sometimes the actual Output window in system preferences doesn't actually display all available options.

Same problem with Sierra and a Dell P2715Q, here. It seems like a display with no audio shouldn't trigger this, but ¯_(ツ)_/¯



With the display connected and no headphones, I used the Sound preferences to change the output to Internal Speakers. Now, at least for this user, the MacBook understands that I never want the sound output routed to DisplayPort.

I suppose you could turn the sound off on your monitor using the buttons. You could also just use a connector like vga or dvi to get rid of sound output.

      I havn't had a Mac for quite a while now, but I'm pretty sure you can't.
      I think somehow it must be possible to deactivate the proper kernel device that's responsible for sound over HDMI/DisplayPort but it's hard to say how easy this can be accomplished, how that will corrupt functionality or how easy it will be to reverse.
      Someone should confirm this but I think you could get a cheap usb sound card, which would allow you to completely ignore the internal soundcard, thus only showing you devices connected to the usb card. Or maybe a software solution, something like AudioMate for example could do the trick.



      UPDATE: NOT WORKING. SEE COMMENT BELOW



      But I would suggest you do the following: It's kind of a strange solution but it'll work and pretty much everyone has the know-how to do it.




      1. Take a look at the pin assignments of DisplayPort

      2. Get yourself a spare DisplayPort cable

      3. Cut it in the middle and solder all the pins back together, avoiding
        the pins connecting audio. (These should be pin 15-17)

      4. Use the cable to connect your display


      5. Be happy!

        I like your thinking, but audio in DisplayPort (and HDMI) travels over the main link, not the aux channel. :(

      • -1 on this "answer". Display port carries power (3.3V, 500mA specifically). Taking a hacked together cable like this can damage your equipment. If you're reading this answer, don't do this.

        May 29 '18 at 22:00













      • You should just take out the entire "not working" part, it does no good to have an answer that doesn't work and worse, it could damage a device. You can just put a note that says "since the audio stream runs over the main channel with video, the cable can't be hacked to remove audio". As it is now the answer says both "Not working" and "it'll work".

                        I like your thinking, but audio in DisplayPort (and HDMI) travels over the main link, not the aux channel. :(

                      • -1 on this "answer". Display port carries power (3.3V, 500mA specifically). Taking a hacked together cable like this can damage your equipment. If you're reading this answer, don't do this.

                      • You should just take out the entire "not working" part, it does no good to have an answer that doesn't work and worse, it could damage a device. You can just put a note that says "since the audio stream runs over the main channel with video, the cable can't be hacked to remove audio". As it is now the answer says both "Not working" and "it'll work".

                      I havn't had a Mac for quite a while now, but I'm pretty sure you can't.
                      I think somehow it must be possible to deactivate the proper kernel device that's responsible for sound over HDMI/DisplayPort but it's hard to say how easy this can be accomplished, how that will corrupt functionality or how easy it will be to reverse.
                      Someone should confirm this but I think you could get a cheap usb sound card, which would allow you to completely ignore the internal soundcard, thus only showing you devices connected to the usb card. Or maybe a software solution, something like AudioMate for example could do the trick.



                      UPDATE: NOT WORKING. SEE COMMENT BELOW



                      But I would suggest you do the following: It's kind of a strange solution but it'll work and pretty much everyone has the know-how to do it.




                      1. Take a look at the pin assignments of DisplayPort

                      2. Get yourself a spare DisplayPort cable

                      3. Cut it in the middle and solder all the pins back together, avoiding
                        the pins connecting audio. (These should be pin 15-17)

                      4. Use the cable to connect your display

                      You should just take out the entire "not working" part, it does no good to have an answer that doesn't work and worse, it could damage a device. You can just put a note that says "since the audio stream runs over the main channel with video, the cable can't be hacked to remove audio". As it is now the answer says both "Not working" and "it'll work".
