geforcefan Posted October 1, 2011 Share Posted October 1, 2011 Hello everybody, after several tryings, I finally get ported the audio drive for OSX Lion 64bit, based on the original source codes from http://scifi.pages.at/ffm-2/ for OSX Tiger. Use KextHelper to install the CMI8738 audio kext or just copy CMI8738AudioDevice.kext to /System/Library/Extensions and type following lines to the terminal: sudo -i cd /System/Library/Extensions/ chown -R root:wheel CMI8738AudioDevice.kext chmod -R 755 CMI8738AudioDevice.kext To test it on running system: kextload CMI8738AudioDevice.kext Maybe you have to clear your kextcache! If there are problems to getting work the kext, just ask me PS: Its a native 64bit kext! Have fun!

nyolc8 Posted October 20, 2011 Share Posted October 20, 2011 I just asked, because I'm using another cmi8738 kext on my lion 10.7.2(64bit) and input not working, but I will try this kext... edit: I have only output, mic and input not working. Input device shows up in sound settings, but it's not working. Do you actually tested input?

WeiSer Posted November 3, 2011 Share Posted November 3, 2011 Thank you, geforcefan. It works great! But, one problem exist... After sleep & wake up, sound is gone. Volume control works, but no sound... Maybe I can use script that unload and load 8738 kext after wake up... but it's annoying.. Can you fix it?

rift Posted January 14, 2012 Share Posted January 14, 2012 It works for me except 5.1 doesn't work. I can get Left, Right, Back Left, Back Right and Sub to work but not center channel. Also it shows up as Stereo in when I got to configure speakers in the audio/midi setup . 5.1 is greyed out Link to comment https://www.insanelymac.com/forum/topic/269375-kext-cmi8738-kext-for-64bit-osx-lion/#findComment-1786336 Share on other sites More sharing options...

ameris_cyning Posted October 8, 2013 Share Posted October 8, 2013 Any chance you could release the source?

ameris_cyning Posted October 13, 2013 Share Posted October 13, 2013 Any chance you could release the source? Source code links are down for the main project I ask again, anyone have the source code? This kext does not work with Mavericks. I would like to recompile it to work with such. 1 Link to comment https://www.insanelymac.com/forum/topic/269375-kext-cmi8738-kext-for-64bit-osx-lion/#findComment-1954061 Share on other sites More sharing options...
granik Posted October 19, 2013 Share Posted October 19, 2013 Input does not working (mic and line-in).

Huckleberry Pie Posted October 23, 2013 Share Posted October 23, 2013 I ask again, anyone have the source code? This kext does not work with Mavericks. I would like to recompile it to work with such. Just stumbled upon it when I tried to snoop around the Wayback Machine for a mirror, so here's a mirror to the source archive: http://www.strawberryforum.org/gtastuff/CMI8738PCIAudioDriver-0.6.4-src.tar.gz Same quirks as with the original, and I do hope someone would make the input parts work, or at least do something ala-VoodooHDA.

Aluminum Ken Posted November 2, 2013 Share Posted November 2, 2013 Any progress on it? My Hackintosh use CMI8738 as well(using optical output) and it needs some Mavericks love It'll be awesome if it works on Mavericks!

ameris_cyning Posted November 2, 2013 Share Posted November 2, 2013 I've given up on it for Mavericks Get a card that works with kx (older sound blaster cards) They are absolutely outstanding and the quality is spectacular. The SNR is at a high level meaning you hear more. 1 Link to comment https://www.insanelymac.com/forum/topic/269375-kext-cmi8738-kext-for-64bit-osx-lion/#findComment-1962500 Share on other sites More sharing options...
Riley Freeman Posted November 2, 2013 Share Posted November 2, 2013 I gave up on my Xonar long ago and just went to onboard in both Windows and OS X. I also use optical out. As it's digital it doesn't make any difference if it's onboard or a dedicated card as there's no digital-to-analog conversion going on.

KickAssGunn Posted November 25, 2013 Share Posted November 25, 2013 How would I recompile the source (above) to work for Input on Mavericks? I have output working... I think that the kext may be picking up the wrong input instead of the Mic. Just tell me what I would need to do in Xcode for the driver to have support for Mavericks? Is it as simple as opening the project and exporting it as a kext for Mavericks?

aicragleon Posted March 11, 2014 Share Posted March 11, 2014 Who has gotten this working in Mavericks and how did you do it? Did you take the source and port to Mavericks? Did you use the kext posted for Lion? I tried the Lion kext and I do not have any audio. I am on 10.9.2 using a cmi8738 card. Thanks. 1 Link to comment https://www.insanelymac.com/forum/topic/269375-kext-cmi8738-kext-for-64bit-osx-lion/#findComment-2002989 Share on other sites More sharing options...
