    How did you get Windows to recognize the DAC? I tried on Windows 10 and 8.1 and both need drivers for the USB device to be recognized.
  2. PointyFox
    "1Bit" is correct for DSD since DSD is only 1 bit. Mine doesn't add extra 0s.

    Oh, I thought you meant in the display. That makes sense.

    I connected the DAC via USB and Windows recognised it as "D50" straight away. I didn't have to do anything else. It worked as D50 ever since.

    I just updated Windows 10 to the latest build and when I connect - BAM - Windows recognize D50 without drivers or setup. Problem persists: D50 display shows sample rate but not bit depth. I am really exhauted - update took 7 hours. Don't know what to do. :frowning2:

    Could that part of the screen be defective?
  8. Technopiper
    That seems to be the only explanation left. I have exhausted all options: tested it on Win8.1, Win10, updated Win10 to latest build, even tested on my Android tablet. Same result: blank space where there should be bit depth. I haven't got a response from Topping yet. Will call tomorrow.

    Mystery solved! I phoned Topping customer service just now, and the person told me that bit depth display has been removed from the latest models of the D50. It used to display bit depth as whatever you set at the player (24 or 32) and not the actual bit depth of the streamed audio. Bit depth display has been removed to avoid confusion. Now I can finally relax and enjoy the music. :)

    Thanks!! Did they mention if there would be a firmware update coming for current owners that will stop displaying BIT depth setting onscreen?
  11. Technopiper
    Not sure if it's the firmware which controls that since there are those with version 1.03 and got bit depth displayed. Can those with 1.03 confirm? I don't think it's a big deal as long as it does not indicate problem with the DAC itself. If you like I would gladly swap with you. :beyersmile:

    Hmmmm. There's 1.03 out there? I can only find 1.02 (http://en.tpdz.net/support.html). Any idea where I can get 1.03? My D50 is at v1.02.

    No swap needed, just curious. :D

    I like seeing what bit depth my computer is outputting.

    I do too. I also prefer not to have my music file's bitrate padded to 24 or 32, which I believe the driver is doing. I know it's just zeros and it is said to have no affect on sound, but it just throws my OCD into a tizzy!! :D

    The player (foobar or jriver) is adding 0s to the stream so that it matches your bit depth setting (24 or 32). The DAC lies at the end of that stream and a change in firmware probably couldn't affect that. There's no way D50 could tell if the original source is 16, 24, or 32bit.
