Can't find correct audio driver - Tiny 11 on Macbook Pro 2012

I came across this post from a few years ago, having what I can see is the exact same problem.

I can't link the post but the title was " [help for uefi win10 sound card with wrong id"]

I'll be really grateful if someone could help me out. Every other driver except this one is installed

Please include the text of your problems. We shouldn't need to go searching in order to help you.

You're absolutely right, that was poor of me.

My computer is a Macbook Pro 2012 mid.
I installed Tiny 11 version B 2(no Sysreq).
I used bootcamp to create a package of the drivers in MacOS and all installed without issue, except the audio driver. It has a yellow triangle over it and shows this generic error
"This device cannot start. (Code 10)
{Operation Failed}
The requested operation was unsuccessful."

The device IDs are:
PCI\VEN_8086&DEV_1E20&SUBSYS_72708086&REV_04
PCI\VEN_8086&DEV_1E20&SUBSYS_72708086
PCI\VEN_8086&DEV_1E20&SUBSYS_72708086
PCI\VEN_8086&DEV_1E20&CC_0403

In the post that I referred to, that person had somehow managed to determine some difference in IDs from the uefi firmware (I don't know how he did that), and that the firmware showed that the card is an intel card, whereas in fact its apparently a cirrus sound card.

They then embarked on checking "if the cirrus sound card is being enumerated by the bios."

After that, I didn't understand what was going on. From what I can see, a solution was not found, and I'd really grateful can help me fix this.

The full thread with all those details is here:

Does the network interface work? Have you brought up Device Manager and attempted to search for a driver in the driver library? Your comment about Cirrus is nonsense; 8086:1E20 is the HDAudio device in the Intel Z77 chipset.

However, to be quite honest, your question is off-topic here. This forum is about kernel programming, not user support.

Also, the bizarreness of trying to run a Windows VM inside a hacked up Linux distribution on a 12-year-old Mac computer cannot be overstated. And:

if the cirrus sound card is being enumerated by the bios

Your Mac does not have a BIOS.

The VM likely has some variation on the standard QEMU emulated bios, which is likely what is providing the HDAudio device.
