C Nuttin Posted June 11, 2007 Share Posted June 11, 2007 My regular analog sound works with appleac97audio.kext, but the SPDIF (coax) doesn't work. Has anyone found a way to get this to work? I didn't have any luck with appleazaliaaudio.kext (no sound at all).

C Nuttin Posted June 16, 2007 Author Share Posted June 16, 2007 Anyone have any suggestions for us? This is pretty much the only reason I even boot back into windows anymore.

MoneyMark Posted June 21, 2007 Share Posted June 21, 2007 I have this issue too, though I suspect the reason there is no help/support for spdif is that very few people actually need it. There are integrated cards that seem to have functional optical outs, I am curious what kext defines that support. Is it in the ac97, azaliaaudio, or HDA kext files? My understanding is the first two are drivers and the HDA is a codec? What have you guys actually done to get this working? Are you sure you modified the azalia kext properly? If anyone knows why this isn't/won't work I'd love to understand.

So I've done some searching as I also have an ALC 850 w/ Optical / Coax out that doesn't work and I came upon this site, which has an installer / driver for Linux...seeing as I have ZERO experience with coding / drivers, I have no clue, but hopefully some nice driver maker could have a look? http://alsa.opensrc.org/index.php/Main_Page and HDA won't work, as the 850 is AC97...doh!

Siegfried Posted August 27, 2007 Share Posted August 27, 2007 SPDIF would be really nice. Maybe it just needs to be enabled in the driver alongside the PCM option? I enabled it in the source code and now I do have an option for SPDIF. I can hear some stuff from the SPDIF connection when switching inputs, but no audio out of there yet. Give this kext a try if you're adventurous and see if it works for you. hxxp://www.MegaShare.com/264165 Put this kext into the PlugIns folder of the AppleAC97Audio.kext.

Just as you said, the S/PDIF is there but it doesn't work. I can hear some things when switching inputs but no sound. i will try and fix this... still searching google / trying to figure out how this works and try to make it work. If i find something, and i get it to work i will post here, until then, keep trying and i hope one of us gets this fixed.
