pattjin Posted April 20, 2006 Share Posted April 20, 2006 Here's a new AppleAC97AudioVIA.kext so you can get stereo out of a VIA 8237R + ALC655 (I don't think the codec part matters as much as the controller) Should work with any VIA 82xx chipset. Hooray! AppleAC97Audio.zip Link to comment https://www.insanelymac.com/forum/topic/15555-alc655-via8237r-stereo-fix/ Share on other sites More sharing options...

My specs: Southbridge: VIA VT8237 (487 BGA) Sound chipset: Realtek ALC655 This is now on the HCL 10.4.5 Wiki Link to comment https://www.insanelymac.com/forum/topic/15555-alc655-via8237r-stereo-fix/#findComment-99914 Share on other sites More sharing options...

skeewiff Posted April 20, 2006 Share Posted April 20, 2006 Jas / Proteo can one of U tell me why my volume slider does not work at all? The rest is OK but my volume slider is useless! I think my chipset is VIA VT8233 not sure I´m gonna check it in Windows now Also any ideas how to add this to a ISO DVD?

Deviant0ne Posted April 20, 2006 Share Posted April 20, 2006 This is awesome! Thanks, I'll give this a try as soon as I get home this afternoon.

JaS Posted April 20, 2006 Share Posted April 20, 2006 20AppleAC97AudioEngine is not compatible with its superclass, 13IOAudioEngine superclass changed? kextload: a link/load error occured for kernel extension /System/Library/Extensions/AppleAC97Audio.kext/ load failed for extension /System/Library/Extensions/AppleAC97Audio.kext/ this is in 10.4.6 so it seems this was compiled on a earlier build,too bad i was getting happy about stereo on this box Link to comment https://www.insanelymac.com/forum/topic/15555-alc655-via8237r-stereo-fix/#findComment-100036 Share on other sites More sharing options...

Proteo Posted April 20, 2006 Share Posted April 20, 2006 skeewiff: Actually I did nothing but replacing the file and repair its permissions with the usual commands. Are you having error messages during boot process? JaS: I'm using 10.4.6 Myzar patch, not sure if it's different from yours at this level. What chipset do you have?

Deviant0ne Posted April 20, 2006 Share Posted April 20, 2006 I just got a chance to try this out, and it's not working at all for me. Now it's saying there are no audio devices on my computer. I replaced the original file with this new one, then did chown -R root:wheel /System/Library/Extensions/AppleAC97Audio.kext - Am I perhaps missing a step? I'm using a VIA 8237 + ALC655 chip, and the 10.4.6 DVD from JaS. Does this not work with JaS' 10.4.6?

skeewiff Posted April 20, 2006 Share Posted April 20, 2006 Proteo: No error on booting just to say that I had this bug before I installed this kext the volume slide didn´t worked.

JaS Posted April 20, 2006 Share Posted April 20, 2006 maybe myzars is using some of the old 4.5 frameworks all i know is in this 4.6 install it's not working.Send me the souce and ill compile it for 4.6 Link to comment https://www.insanelymac.com/forum/topic/15555-alc655-via8237r-stereo-fix/#findComment-100068 Share on other sites More sharing options...
Proteo Posted April 20, 2006 Share Posted April 20, 2006 Copy and paste the new file to /System/Library/Extensions/. Choose authenticate in the dialog and enter your password. Replace the file. Then open Terminal and type: sudo -s (enter your password) cd /System/Library/Extensions rm Extensions.mkext Extensions.kextcache (no problem if one or both files don't exist) chown -R root:wheel *.kext kextcache -k /System/Library/Extensions (exit terminal) Applications > Disk Utility > select your volume and repair permissions Quit and reboot. That's exactly what i did and it worked like a charm. 1 Link to comment https://www.insanelymac.com/forum/topic/15555-alc655-via8237r-stereo-fix/#findComment-100071 Share on other sites More sharing options...

pattjin Posted April 21, 2006 Author Share Posted April 21, 2006 You could try just copying the file AppleAC97Audio.kext/Contents/PlugIns/AppleAC97AudioVIA.kext/Contents/MacOS/AppleAC97AudioVIA, since that's really the only part that changed. Of course, make it root:wheel, and all the permissions and stuff like that. Now to see if I can figure out the other channels and maybe the onboard VIA8237 Ethernet as well.

skeewiff Posted April 21, 2006 Share Posted April 21, 2006 For those that this work: a) Is the onboard audio present in the system profiler? Does work the volume slider?

JaS Posted April 21, 2006 Share Posted April 21, 2006 So no matter what this kext wont work under your install DVD JaS? As of this moment anyway...? well my install uses all the frameworks from 10.4.6 so it seems the user compiled this under myzars v3 10.4.6 update and it used some of the older frameworks.myzars ppf4 uses the 10.4.6 frameworks also.if he would send me the source I would compile it so it works on this version 10.4.6,too bad i didn't use the old frameworks heh ... lol Link to comment https://www.insanelymac.com/forum/topic/15555-alc655-via8237r-stereo-fix/#findComment-100302 Share on other sites More sharing options...

Deviant0ne Posted April 21, 2006 Share Posted April 21, 2006 Eh, newer (frameworks) is better right? Is there some way to take that kext apart? I have no idea if that's even possible... I'd lend a hand if for some reason you needed it.
