    Can anyone with a proper driver for their Xmos XU208 device please confirm if you have the 16-bit mode available in the control panel like the following? I only have 24 and 32 with the Matrix X-SPDIF 2 and curious if this is something that was completely removed by XMOS in the latest driver/chip or the absence of the 16-bit mode is specific to Matrix?

    I don't even have that tab on the control panel window.

    Interesting, what device do you have? My screenshot above is for an older XMOS chip but I do have a similar tab for the Matrix X-SPDIF 2 but can't choose 16 bit there, only 24/32. I'm hearing XMOS removed the 16-bit setting in the latest driver/hardware and want to confirm it.

    EDIT: I see you have Breeze Audio, so is this the driver that Windows 10 loads automatically?

    That is exactly what i read and that seems to be why i don't see an option for format to begin with. While accessing the Breeze Audio USB XMOS U8 from a playback software (Media Monkey etc.) i get the 16bit, 20bit and 24 bit option max 192 khz

    So your Breeze using XMOS U8? This is previous generation. I have that option for the Matrix X-SPDIF 2 which is based on the XU208, but can't select 16-bit as it's missing.

    The picture I posted is from a M2Tech XMOS module/driver in my other DAC, I think it's also based on the older U8, so the setting is there but if your panel is from the default Win10 driver sounds like this feature has been disabled there as it's often the case with default windows drivers that have reduced feature set as compared to those you get from the actual hardware vendor.

    I had first installed the suggested vendor driver however since it was an eval driver it emitted a beep every 10 mins or so after an hour of playback. So i decided to try out the Win 10 driver. Yes this is based on the older U8 chip

    Apparently Breeze doesn't supply drivers so your stuck with whatever is in Win10. You might be able to use a driver from another device that's based on the same chipset, I have yet to find a confirmation it is possible.

    So far I am testing the win native driver to see if it will serve the purpose then i will hunt for devices with identical U8 chipset and try if their drivers work.

    Please report back if you can find a working driver, I have a suspicion XMOS drivers can be locked to hardware.

    I shall keep you posted.Currently the native windows driver can only serve 24 bit.

    I see both 24 and 16 bit modes available when the M2Tech driver is set to 24bit, and only 16bit when it's set to 16bit, which makes sense. It does look like the Windows default driver is dumbed down.

    With the Windows 10 xCore USB 2 driver, under the advanced tab, I show 16/44100 thru 24/384000

    I did send a note to the seller concerned about the driver. They sent me the Smuma Digital XMOS XS1-U8 MFA (ST) v 2.19 driver. It seems to work fine including the ASIO driver for JRiver which I typically prefer over WASAPI. The Windows 10 xCore USB 2 driver only worked with WASAPI.

    What "Output" options are available on the "Format" tab in the XMOS driver control panel with that driver?

    Under the advanced tab, 16/44100 thru 24/192000

    I know in my case with my Elyse DAC, connecting the Breeze to the RCA input, it will show 24/192000 available. When I hook the Breeze to the BNC input it is limited to 24/96000 and then the advanced tab only shows the highest at 24/96000. So the options available from windows also changes depending on the DAC you are using with the Breeze.
