Restoring Stereo Output on MSI Z490 Tomahawk
If VoodooHDA is treating your stereo speakers as a 5.1 system on macOS Tahoe, you need to modify the Info.plist inside the kext.
The Fix:
- VoodooHDA Settings: Right-click
VoodooHDA.kext> Show Package Contents > Contents >Info.plist. - NodesToPatch: Find the
NodesToPatchsection. You need to 'untask' the Orange and Black jacks by setting theirConfigDefaultto0x40f000f0(Disabled). - Vectorize: Set
Vectorizeto True to improve audio processing efficiency on your i9-10850k. - Rebuild Cache: Run
sudo kextcache -i /and reboot.
Original Question: "Tahoe with VoodooHDA channel down mixing"
Tahoe with VoodooHDA channel down mixing
Hi all,
I just upgraded from Sequoia 15.7.7 to Tahoe 26.5.1 over the weekend. One of the issues I ran into was the fact that AppleALC doesn't work in Tahoe any more, so I had to migrate to VoodooHDA. That's functioning, but I'm having a problem with audio channels, I think.
In the previous setup, the AppleALC system knew that I had only a pair of speakers, so multi-channel audio (5.1, etc) were downmixed to stereo.
With VoodooHDA, I don't seem to have the right set of choices for audio outputs. I'm given the following: * 5.1CH (Green+Orange+Black Rear) * Headphones (Green Front) * SPDIF-out (Black Rear)
My speakers are only plugged into the green audio jack on the back, so I'm only getting L+R through that.
This is my hardware:
| Hardware | Details |
|---|---|
| Processor | i9-10850k |
| Motherboard | MSI MAG z490 Tomahawk |
| GPU | ASUS Radeon RX 6600 XT 8GB |
| OpenCore | 1.0.7 |
| VoodooHDA | 312 |
| macOS | 26.5.1 |
For the VoodooHDA install, I installed it in /Library/Extensions per the instructions, but I've not done any other configuration. I suspect that I need to specify a layout or something like that somewhere.
Does anyone have any hints on what my configuration might be missing to allow me to use only the rear Green jack?
Thanks!
