No Audio Devices - Realtek ALC AppleHDA [Guide]

[toleda]

No DSDT.

OK. Codec is not enabled, no audio until you see DPCIManager/Status/Codec ID

Ok...er, does this mean I must use a DSDT then? And if so, any idea how that other guy got his audio working with your script - on a board identical to mine - without a DSDT?

Thanks so much for your help (and patience)!

No. The other guy has a codec visible to OS X, you don't. Enable the codec.

Enable the codec.

Ok...how? A setting in Clover perhaps? (In Clover Configurator I see Devices->Audio is blank; should I enter something there before trying anything else?)

I followed your troubleshooting steps in post #1:



1. OS X Version (running 10.10.3)

2. 10.10 and newer/Boot flags​

1. Clover/config.plist​

1. Mandatory Add: config.plist/Boot/Arguments/kext-dev-mode=1 *done* according to Clover Configurator​

2. Remove: Boot/Arguments/npci=0x3000 *done* according to Clover Configurator​

2. HDEF Verification/IORegistryExplorer

1. IOReg/Search: HDEF - I see AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/HDEF@1B​

2. If IOReg/HDEF present, see 3. Audio_ID verification​

3. Audio_ID verification/IORegistryExplorer

1. Search: HDEF​

2. IOReg/HDEF/layout-id = hex(Audio ID)​

3. Locate: layout-id​

4. Verify layout-id: - I see <00 00 00 00>​

4. Not valid (<00 00 00 00>), select one method and implement​

4. [Guide]-Add HDEF-Clover.pdf (this is what I want, right?)​

[Guide]-Add HDEF-Clover.pdf:
I. IOReg/HDEF Verification

A. IOReg/Search: HDEF - yes it's present, already did this above​

B. If IOReg/HDEF present, see II. IOReg/Audio_ID verification​

II. IOReg/Audio_ID verification

A. Search: HDEF​

B. Locate: layout-id​

C. Verify layout-id: - obviously I still see <00 00 00 00>...​

- <00 00 00 00> not valid - ok what now??? I’m pretty sure my motherboard uses Audio_ID 1, but this is saying not valid…Should I proceed with step IV and enter "1" anyway even though this says not valid? What step did I miss?​

See Post #1/I. No Output Devices Found/2. HDEF Verification/IORegistryExplorer/3. If no IOReg/HDEF:1. IOReg/Search: @1B
2. Add dsdt/HDEF
