I feel i am in a dead end but i dont want to giveup. Any hint will be high appreciated. To check what happens during the boot process, check the log. One way to do it: Open the program, click on the Logs icon inside the app, and choose the system. There goes all the info of the kernel during the boot process. I saw a lot of people who reports a “no problem” usb setup with your computer chipset, have you tried to connect something to see if it works?

Maybe its just a warning message. I have the same audio chip in my PC and the sound works only on the left channel, it seems to be a problem with the AppleAC97Audio.

Thank you jcordero for your reply. I was on the way to think that this is a zombie forum.

I am at work now but first thing when i go alc65 i will check system. As for usb when I connect a memory stick nothing is “mount” but i have power on usb port the led of memory stick is on. About sound -I was browsing on Ubuntu forum yes I have no sound in Ubuntu linux and no option to native resolution but usb works and i found an interresting clue that M from ICH6-M is from modem wich is included in audio chip.

In fact what i don’t find in this forum is the combination ich6-m and alc codec that I have. Anyway I am anxious to go home and check system log and now that i know what ehci and uhci are maybe i will find a way After many tries i discovered that i have sound in vmware if i install osx jas System profiler catasheet nothing in audio built in section but i have sound in system preferences.

Problem is that if i want to boot native i must change iousbfamily. After that my sound dissapear and in system prefererences show “no output devices found” and output volume is mute and is greyout and canot be unmuted.

Anyone know how can i have at least sound back? As i mentioned in the subtitle of this post ” there is a will But now i need some help. I read in wiki HCL-Portables that some of guys managed to install without problems and they have sound and usb on similar or identic configurations chipsets, controllers,processors with mine. Unfortunately datzsheet indications were vague like: So what kexts i need to modify? I managed so far to load AC97Audio. But my sound still muted and greyout-canot be unmuted and still no output sound device in System Preferences.


I am using a Shuttle Box and have the same thing. No audio, everything greyed out.

I have USB and Ethernet onboard. I am using uphuck I am still searching, and will let you know if I can find something that is working You need to be a member in order to leave a comment.
