Yes, it's a known issue that the sound card is non-resettable. The
really good is is that this generally isn't a problem.

  If through your testing you start having problems, you might need to
stop/start the VM, and in some cases, fully shut down the machine. I did
tons of testing, and very rarely did I need to do anything more than
restart the VM. Only twice did I need to shut off the entire laptop.

Anyway, getting Windows to use the right driver is a bit tricky, but it
can absolutely be done. I don't have the same machine, but looking at
your alsa-info, this should mostly work.

I don't have the URL for your laptop, but here's the Lenovo version as
an example:
https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/legion-series/legion-7-15imhg05/81yu/81yucto1ww/mp1t35d3/downloads/driver-list/

Find the equivalent part of the Lenovo site for your model and then
download your sound driver.

When opening the driver, choose to extract the driver (it won't hurt if
you also install it).

Anyway, here are the instructions I posted earlier in this bug:

You need to force the device expanded above to use the RealTek driver. I was able to force it by *extracting* rather than installing the sound driver from the Lenovo site. Selecting update driver on the sound device listed under "Sound, video and game controllers", and from there I did:
"Browse my computer for drivers"
"Let me pick from a list of available drivers on my computer"
"Have Disk"
Browse to: C:\Drivers\Audio\201211706.15485923\Realtek\Codec_8975.1\HDXLVSST.inf
Press Ok
You should see "Realtek High Definition Audio(SST)" as an option. It's the only option for me)
Next
Yes
Restart the VM when prompted

Hopefully after these steps, you'll see the "Realtek High Definition
Audio(SST)" device in device manager as your sound card and you'll get
sound from windows.

By getting a Win10 VM running with the JCS Qemu means you're a good
chunk of the way done.

PS: I looked into RtHDDump_V236 and I don't think it's anything I needed
for my particular case. It seems it can be used to figure out what pins
should be connected to what. We'll see if you need any of that, but not yet.
