Is there some way I can help to get Realtek/tas working for the Lenovo
Slim Pro 9i (named Yoga Slim 9i outside of the US)?

On my Manjaro install, the top speakers work (although I don't think
they're amplified?) and the bottom subwoofers are off.

I've managed to get qemu working for sniffing following this guide:

At one point, Win10 in qemu had sound working similar to Linux (only
top-firing, maybe unamplified), and I saw event logs, but I don't
remember the driver. I might need to do a clean install at this point.

When I try to install the driver in qemu in win10 or win11, I get a
bluescreen. Windows is using Realtek Semi Corp ver 6.0.9553.1.

I have a separate grub entry to boot without sound (for qemu sniffing)
using these flags:
modprobe.blacklist=snd_hda_intel,snd_sof_pci_intel_tgl pci-
stub.ids=8086:51cf iommu=pt intel_iommu=on

I'm not sure if that's enough. Happy to help in any way!
