Thanks for the info. Interestingly, both MPlayerX and VLC now have SPDIF/Encoded Digital Audio Passthrough selections in Preferences making the patch unnecessary for those players.
Thanks for the feedback. No ML MultiBeast ALC8xx AppleHDA.kext supports Encoded Digital Audio natively. Early versions (Lion) did, however, significant user complaints (excessive popping) lead to an alternative patch (much quieter) at the expense of Encoded Digital Audio. I found many more users connect analog speakers to their systems than connect optically to receivers.I have not tried the above patch, but I have just tried your new ALC8XX (889) from the latest MultiBeast with DSDT edits and there is no Encoded Digital option in ANY supported app. I know you were referring to ALC885, so just an FYI.
Applied the patch (first using Terminal as per your guide, then I tried using Hex Edit and replaced 85 08 EC 10 with 89 08 EC 10) and I still can not enable Encoded Digital.
Just a little bit of constructive criticism, why do you not edit all of the ALC8XX kexts to have DTS/DD surround natively? To me this makes no sense as virtually everyone uses Optical out for encoded audio. What are the benefits to having this NOT the default for your ALC8XX Audio ID:1?
Here is the AppleHDA.kext I am using; it was installed using MultiBeast, then edited as per your guide. Maybe I overlooked something.
I also included a patched AppleHDA from 10.8 (I think) that I did way back. It works 100% with the DSDT from the database. It's sloppy and bloated, but works. Maybe you overlooked something.
See Note 1 in Post #23 above. Apply the edits as described in the Customization guide.I could use some help with getting encoded audio (step 8 in the 0.4 guide). When I try the steps, I get no audio device in sound control panel.
Were you successful with the 2 wire spdif edit? I am curious if your kext will work for me!In Audio Midi:
Built-in Digital Output
Format: 48000 (44100 and 96000 also available)
2ch-24bit Integer (2-ch 20bit Integer and 2-ch 16 bit Integer also available)
In VLC:
x Use S/PDIF when available
Force Detection of Dolby Surround: On
*It might be worth also pointing out that my HDMI audio has also stopped doing DD/DTS via VLC to my amp - pretty sure this started happening after applying edits to AppleHDA.kext but can't be 100% sure.
I have tried MPlayerX and this is doing the passthrough fine on HDMI and optical.
