Hello, Here is a screenshot of the dev manager. You will notice the XMOS DFU showing as no driver. Also you will notice XMOS USB Audio 2.0 shows as driver installed and working.
Even with XMOS DFU indicating no driver installed, the Tone Board appears to work. It is my understanding that the XMOS DFU is for loading and retrieving firmware from the Tone Board and not required for sound.
This is an excerpt from this PDF from XMOS…
“The DFU loader is a flash device firmware upgrade mechanism.”
It has been a long while since I flashed firmware to the TB, so I don’t recall for certain, however, I would assume TB firmware update package will include a driver for XMOS DFU.
The screenshot of my Win10 DevMan…
I just connected the TB to my Win10 laptop, Windows installed the Window’s driver. If you already have the Theyscon driver installed, uninstall it from the devman, select the delete option if available…
I deleted Theyscon driver but instead of xCORE USB Audio 2.0 I see ‘Khadas Tone Control’ in Device Manager
I have sound without driver but I can not play 24 bit files because I think proper windows default driver is not installed and I can only see 32bit values in sound control panel. It is buggy. There is not 24bit in the list like I had before with Theyscon driver (screenshot below)
I updated the TB firmware to 1.04, after doing that the TB shows like yours, "Khadas Tone Control, on Win10 driver. I do not recall seeing 24bit either.
A Khadas Team member may be needed to explain why that changed from Theyscon driver.
We both have the same issue. Colleague @RDFTKV got it after upgrading firmware to 1.04. I have it from the beginning because my Tone Board came with firmware 1.04 preinstalled.
My khadas came with firmware 1.04 preinstalled and I can’t see 24bits format either in device manager, but why don’t you just set up 32bits and forget about it?
That is not good solution in any possible way and there are issues. You can not play native 24bit files etc. using WASAPI if you keep using Windows driver and latest firmware.

If you test Tone Board using latest firmware and Windows 10 UAC driver it will behave exactly like mine. I have some work devices where I have not permissions to install Thesycon driver, so I am stuck with Windows Driver and by using it I can not play 24bit files as you can see above
