USB Start-up Problem (aka the Audio problem)

Status
Not open for further replies.
Thanks for this thread - otherwise I would have pulled out any hair that is left on my head by now.

This fixed most of my issues - however I still get a weird kind of "bump" noise whenever my sound goes idle for a while and then I do something w/ output - kind of like it's waking up but then there's a glitch somewhere.

Motherboard - Gigabyte GA-77-DS3H
Codec - ALC888B
(Also using a NVIDIA GeForce 210 PCI card)

Another GeForce 210 user here.

My issue started with ML. Using the latest Multibeast and installing according to Moarish's guide (kexts: 3rd Party Sata, ALC887, RealtekLan, FakeSMC) would cause long boots and unresponsive KB/Mouse for several minutes. Sackboyx and myself narrowed the issue down to the Audio kext. Using the ALC887 audio from Multibeast 5.0.2 solved the issue: fast boot and working sound.

Updating to Mavericks with Multibeast 6.0.0, the issue was still half present. Boot times were again long, but KB/Mouse worked fine once booted. I discovered this thread and used the audio_ssdt-hdae-1 and deleted HDAEnabler1.kext and boot times were now fast. I also had to put my PState info in the SSDT since Generating Pstates doesn't appear to work when using an existing SSDT.

My system is as follows:

GA-B75M-D3P
Xeon 1230v2
GeForce 210
ALC887

Kexts: AppleHDA, FakeSMC + Plugins, 3rdPartySata, Lnx2Mac Realtek, Trim Enabler

I do get some sound assertion messages in the kernel log, but they don't appear to be a problem. With the SSDT enabler boot is fast and sound works fine.
 
Help, what I am doing wrong? Also a geforce 210 user. Still cant get audio to work. I downloaded audio_ssdt-hdae-1.zip, renamed SSDT-1.aml to SSDT.aml and moved it to /Extra ( i didnt have SSDT.aml to begin with). Next, I enabled ssdt by editing boot.plist (see below). Rebuild kernal cache, no errors, then reboot.

Sorry I did not make it clear. I had audio working but I had the syptoms of long boot and mouse/kb not responding after 5 minutes. I followed your procedure as workaround. I ended up solving the issue of the long boot and kb/mouse not working, but now I dont get sound at all.
 
Thanks. Found my problem. Didnt have to use your workaround at all. Reinstalled from scratch, applied with DSDT ALC885 in multibeast. No sound. usb works and no slow bootup. I checked the dsdt/HDEF and sure enough, layout ID was 0x0C. Changed to 0x01, compile and save. Restart , problem fixed.

Thanks again toleda for all your useful posts. Im kinda new to all this osx86, i learned a lot.
 
I tried everything in this thread and am unable to get this to work for me. I'm using an Abit IP35 Pro motherboard, Core2Duo CPU and have a Geforce 210. The only way I can get Audio to work is if I use the ALC888 Legacy version with the HDAenabler, but then it boots painfully slow. Without the HDAenabler it boots how it should, but I can't get audio to work. I tried both files #1 and #2, no go.

Is there no SSDT version for the ALC888 Legacy? Any workaround for my exact situation or am I missing something?
 
Is there no SSDT version for the ALC888 Legacy?
The ssdt does not care what codec is installed. Install the ssdt (#1 file) with the working 888Legacy. Reply with dsdt, ssdt, ioreg, org.chameleon.Boot.plist.
