BSpider94 Posted July 29, 2016 Share Posted July 29, 2016 Hello, I'm using AppleALC, sound working great but mic is not working. I'm using Layout 3. my machine is Lenovo G510 (i7-4702MQ, HD4600, 1366x768) (Clover). The codec is Conexant CX20757. IOREG and Info.plist attached.

llamafilm Posted July 30, 2016 Share Posted July 30, 2016 I want to try this on my system, but I read this in the instructions: AppleALC does not deal with layout-id values, it expects you to provide a correct DSDT(SSDT).What does this mean? I don't know what DSDT I would need for my sig system. I have an ALC1150, which says it is supported. Link to comment Share on other sites More sharing options...
al6042 Posted July 30, 2016 Share Posted July 30, 2016 I guess you use Clover as the bootloader... Make sure the "FixHDA" is activated and in "Audio Inject" the number "1" is set. With this you will not need a patched DSDT, if you do not already have one, which could be again patched for the "layout-id" Link to comment Share on other sites More sharing options...

Tried "FixHDA" and set the layout to 1. it doesn't work. Also tried FixHDA with Layout 3, doesn't either. Link to comment Share on other sites More sharing options...
al6042 Posted July 30, 2016 Share Posted July 30, 2016 Did you try another approach of getting audio to work, which might is still lingering on your box? Where did you put AppleALC? In one of the kexts directory from Clover? Please use the following command to create a txt-file on your desktop and post the file afterwards: kextstat > ~/Desktop/kextstat.txt Link to comment Share on other sites More sharing options...

AppleALC is in EFI/CLOVER/kexts/Other. I was using Yosemite with VoodooHDA, everything was working fine. kextstat.txt Link to comment Share on other sites More sharing options...
al6042 Posted July 30, 2016 Share Posted July 30, 2016 For the 20757 there is only AppleALC support with Layout-ID 3. If your microphone is not working, you have to wait until the developers are able to change that. Does it work if you use an external microphone via a headset? BTW: the request for a kextstat.txt was not for you, but for the user @llamafilm Link to comment Share on other sites More sharing options...

llamafilm Posted July 30, 2016 Share Posted July 30, 2016 Hi, thanks for your help. This kext is not working for me. I see the output devices, but the system won't play any audio. I'm using iTunes to test. When I hit play, it never plays, and the playhead stays at zero. When I switch to HDMI output, the playhead starts moving, and I hear some audio through my HDMI monitor, but it's very crackly. I installed /S/L/E/AppleALC.kext with Kext Wizard. Set FixHDA and Audio Inject = 1 in config.plist. I previously had tried toleda's script, but I think I have removed all traces of that. I restored native AppleHDA.kext, removed /L/E/realtekALC.kext, and disabled the Clover patches. I'm not sure how to do a codec dump, but here is kextstat output. kextstat.txt Link to comment Share on other sites More sharing options...

llamafilm Posted July 30, 2016 Share Posted July 30, 2016 starts without cache and after rebuild. restarts if it does not work, test layout 7 I'm not exactly sure what you mean. Does that mean use -f boot argument in Clover and then run sudo touch /S/L/E ? Link to comment Share on other sites More sharing options...

llamafilm Posted July 30, 2016 Share Posted July 30, 2016 How to I try a different layout? I see there are several mentioned in Info.plist. Do I have to edit that? Link to comment Share on other sites More sharing options...
gengik84 Posted July 30, 2016 Share Posted July 30, 2016 in config.plist change 1 ---> 7 Link to comment Share on other sites More sharing options...
llamafilm Posted July 30, 2016 Share Posted July 30, 2016 Oh I see. Ok, tried that, but it had no effect. Link to comment Share on other sites More sharing options...
gengik84 Posted July 30, 2016 Share Posted July 30, 2016 Have you used previously VoodooHDA? Check do not have Realtek.ALC.kext in EFI folder Link to comment Share on other sites More sharing options...
llamafilm Posted July 30, 2016 Share Posted July 30, 2016 I've never used VoodooHDA. Nope, don't have realtekALC. I did remember just now that I had two SSDTs from toleda in the EFI partition. I deleted them just now, and rebuilt the kext cache, tried both layout 1 and 7. Same problem. But now HDMI audio disappeared of course, because that was enabled by the SSDT.

al6042 Posted July 30, 2016 Share Posted July 30, 2016 When in Clover Boot Menu use Space bar and then go to "start Mac OS X without caches"... Link to comment Share on other sites More sharing options...
llamafilm Posted July 30, 2016 Share Posted July 30, 2016 I think that's the same thing as -f boot flag? Anyway I tried it, but it makes no difference. Still iTunes won't play. In system.log, I see this, and the last two lines repeat hundreds of times. Does that mean anything to you? 7/30/16 13:47:31.000 kernel[0]: Sound assertion in AppleHDAController at line 6576 7/30/16 13:47:31.000 kernel[0]: Sound assertion in AppleHDAEngine at line 1863 7/30/16 13:47:31.000 kernel[0]: Sound assertion in AppleHDAController at line 6649 7/30/16 13:47:31.000 kernel[0]: Sound assertion in IOHDAStream at line 384 Link to comment Share on other sites More sharing options...

The codec is Conexant CX20757. AppleALC is in EFI/CLOVER/kexts/Other. Audio Layout is 3.

achamate Posted July 31, 2016 Share Posted July 31, 2016 I dont have any clue on where to begin and how many hours I need to do this, and if sucessful for sure at all. All I know ALC269 is not working on i5 3230m Samsung laptop. Wifi solved with external usb, Audio solved with external usb. Rest of drivers solved with kext utility. If someone has an easy fix I go for it. In the meantime I´ll try HDMI, wish me luck. Capy 10.11.6 and Windows 7 in just any case . Thanks. Link to comment Share on other sites More sharing options...
