USB Start-up Problem (aka the Audio problem)

[tehsuck]

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

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.

Off topic. This thread is for users with working audio. See Mavericks: No Audio - Realtek ALC AppleHDA

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.

I dont get sound at all.

See Post #25.

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?

 

[toleda]

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.
