hitman478 Posted February 28, 2015 Share Posted February 28, 2015 Hi, I am trying the hole day to get my sound working. I know that is a ALC269 chip. My OS Version is 10.10.2 I have tried to edit the DSDT and the AppleHDA Kext but it dind't work I will upload my own modified DSDT and the original DSDT. When I run the Tool System Info it also didn't detect the ALC269 Sound card. When I try the Voodoo HDA then everything works but it always have a high input noise on boot. I hope someone can help me. Thanks. org_dsdt.zip mod_dsdt.zip Link to comment Share on other sites More sharing options...
Allan Posted February 28, 2015 Share Posted February 28, 2015 Do you use kext-dev-mode=1 boot argument ? And applied DTGP method in DSDT too? Link to comment Share on other sites More sharing options...

hitman478 Posted March 1, 2015 Author Share Posted March 1, 2015 I tested now the kext from your link and the ALC269VB worked for me one time and then the system crashed and then sound didn't work anymore and then I did another reboot and then I got sound again. I attach a screen how it looks in the Device Manager. I also attached the codec dump that I made. codec_dump.txt Link to comment Share on other sites More sharing options...

hitman478 Posted March 1, 2015 Author Share Posted March 1, 2015 Now I have another problem but I don't know if it is related to the sound card. When I use the program teamviewer ad when I start a meeting then I have very quiet sound. When I close teamviewer then sound is back to normal.
