sigmaris Posted August 18, 2005 Share Posted August 18, 2005 I have a P4 laptop with an Intel ICH4 chipset (I think the model number is 82801 or similar). It works with OS X86 if i pass the option platform=X86PC at boot and patch it for SSE2. However the sound does not work. I followed the procedure of adding the PCI IDs in the wiki, but i found the ids (vendor 8086 and device 24C5) were already in the list under ICH4, as would be expected. The AppleAC97AudioIntelICH kext is auto-loaded on startup but no audio devices appear in system preferences. Does anyone have any ideas on how to get the sound working? is it possible that only the ICH5 drivers work because that was the chipset in the developer kits?

markitoxs Posted August 18, 2005 Share Posted August 18, 2005 I also have ICH4 and it is working, without doing nothing special. I also have my vendor and device id already in Info.plist. The problem is that The sound works, but very very bad, like if i was on an old computer, like slow, I don´t really know where the problem can come from... any suggestions, would be really appreciated. I tried everything, i have read the fixing from the wiki, the ones in concretesurf, in 360hacking, and no idea... Thx in advance.

markitoxs Posted August 18, 2005 Share Posted August 18, 2005 I found the solution!!!! At last!!! platform=x86pc The file to edit is /Library/Preferences/SystemConfiguration/com.apple.Boot.plist just find this part and write platform=x86pc BLA BLA CODE CODE CODE <key>Kernel Flags</key> <string>PUT IT HERE</string> Save changes and reboot. Done! Link to comment https://www.insanelymac.com/forum/topic/452-intel-ich4-audio/#findComment-3183 Share on other sites More sharing options...

I know in Knoppix it uses the i810 driver. I would really like to have sound, so if anyone could help us out it would be much appreciated. Edit: I'm booting from a Gateway 4530GZ laptop, 1.6GHz Pentium M (no SSE3).

natew Posted August 23, 2005 Share Posted August 23, 2005 It didn't work for me. I have a Gateway 4540GZ. With the un modified I can adjust the volume, but nothing comes out. With it modified nothing comes out and I can't adjust the volume like before.

FloatingFatMan Posted August 28, 2005 Share Posted August 28, 2005 Has anyone got this particular chipset working yet? I have everything else working fine, even networking, but no audio I've been through every thread and have trimmed my Info.plist file down to just the ICH4 entries for the 0x24c58086 device and still no sound. and no audio device listed... On a verbose startup, I get the following error: AppleAC97AudioIntelICH : failed to create interrupt event source I get this 5 times, even though I've stripped all but the ICH4 stuff out of the kext... Any ideas? All almost ready to wipe XP and it's only this stopping me!

slydecix Posted August 29, 2005 Share Posted August 29, 2005 Same problem, I'm on a Toshiba M200 Tablet... 0x24c58086 under ICH4 and it's not getting detected Link to comment https://www.insanelymac.com/forum/topic/452-intel-ich4-audio/#findComment-8904 Share on other sites More sharing options...
mooseboy Posted August 31, 2005 Share Posted August 31, 2005 I am also with an ICH4, and I can get the kext to load and the device to show up in the sound system preferences. I only have 2 channels available for the midi trick (Utilities -> Audio Midi Setup), so I can't change where front left and front right are routed to. Not that it would matter as I'm using a laptop. Neither headphone jack nor internal speakers actually emit sound though.

VaiOSX Posted September 16, 2005 Share Posted September 16, 2005 I got the same issue : 0x24c58086 on Vaio PGC-TR1/B The sound is working, but it is very low and only in the 3.5 jack plug (headphones).

docOSX Posted October 10, 2005 Share Posted October 10, 2005 bump I'm having this problem too. I can adjust the volume, the MIDI app see's the card AC97 (PCM). Just no sound. Now I remember in a few Linux distro's I had to tweak the IRQ's to get it to work. If only I could remember .. EDIT: This is on a Gateway 4026GZ.

I found that on my older ich4 system that I had to make sure that the AppleIntel830.kext was loaded before I was able to get sound. Find the thread on this board about adding this to your setup.

DrJägermeister Posted October 11, 2005 Share Posted October 11, 2005 (vendor 8086 and device 24C5) Good news: you sound should work, just replace you kext: Can you boot without "-x"? It's important I have no sound when I boot with "-x" Replace the kext in /system/Library/extensions with this one (unzip it first): http://forum.osx86project.org/index.php?ac...ype=post&id=528 You don't need to configure it, 24C58086 is still configured in ICH4. If you still don't have sound after a reboot so try to load the kernel extension yourself: # sudo -s # chown -R root:wheel /System/Library/Extensions # cd /System/Library/Extensions/AppleAC97Audio.kext/Contents/PlugIns/ # kextload AppleAC97AudioIntelICH.kext then clean your extensions cache: # rm /System/Library/Extensions.kextcache # kextcache -k /System/Library/Extensions Reboot and hope that you have sound now.
