maccerj Posted January 15, 2015 Share Posted January 15, 2015 Good day, after searching endlessly through forums and trying various ways I now need your help. My issue is that I need to output sound over my macbook airs mini displayport, the setup looks like this: Macbook -> mini DP -> mini DP / hdmi adapter -> hdmi switch (with toslink extractor) -> Optoma hd 20 The toslink is connected to a separate DAC. Since the edid from the Optoma is telling the macbbook that sound is not supported I want to override this. So far I have dumped the projectors EDID with Darwin Dumper, then modified the dump with AWEDIDEditor, the modified output file is a bin-file. How do I use this file to override the old EDID? Looking forward hearing from you. Link to comment Share on other sites More sharing options...
jamiethemorris Posted January 16, 2015 Share Posted January 16, 2015 Osx has a folder for display overrides. Check this link: http://www.insanelymac.com/forum/topic/290077-get-your-display-recognized-and-working-as-imac-thunderbolt-macbook-pro-or-cinema-hd-display/ the last few steps are the ones that are relevant. As you can see, you need to have a folder named with your displays vendor id in the overrides folder, and your edid named with your display's device id.

maccerj Posted January 19, 2015 Author Share Posted January 19, 2015 Thank you for your reply Jamie, Still having difficulties converting the bin-file to correct format. I've created a folder in the overrides directory called "DisplayVendorID-3e8d" and in that folder created a file called "DisplayProductID-20" Can you help me out converting the file to correct format? http://speedy.sh/JDjPS/EDID2.bin Also: Will I be able to output sound over mini-dp while the projector is turned off? If -no, how can I solve this? Cheers Maccerj Link to comment Share on other sites More sharing options...
