Nintendo switch and Vivaldi dac/upsampler

Hi Anupc,

Thanks again for replying!

I don’t think you can. As far as I know, the 2 x USB ports on the Dock are for charging the unit, for a USB-LAN adapter or USB-Keyboard, etc., but, if I’m not mistaken, they don’t supports Audio output to any DAC (hence the need for an external HDMI → Audio adapter).

Unfortunately I am using USB port for audio output now. As you can see in the picture:

If you mean your audio via TOSLink is dropping out every few seconds, thats likely because your Upsampler/DAC clocking is configured incorrectly. They need to be sync’ed to the incoming audio stream on that TOSLink input;

• If you’re connecting directly to the DAC’s TOSLink port (SPDIF4), then set the DAC’s Sync mode to “Audio” for that TOSLink input.
• If you’re connecting to the Upsampler’s TOSLink input, then both the Upsampler and DAC need to be sync’ed to that TOSLink input;
  –Connect your Upsampler’s Word Clock OUT port to the DAC’s Word Clock IN3 port with a 75 Ohms BNC clock cable
  –Set your Upsampler’s Sync Mode to “Audio” for that TOSLink input
  –Set your DAC’s Sync Mode to “W3” (Word Clock 3)

Thank you so much for your advices and apologies for my poor English.
The sound dropping out, but not so often.
And I connect my DAC and Upsampler with Clock, that’s why I said I can turn on ‘DAC buffer’ by using Upsampler’s interface, otherwise the sound will be delayed.
But if I using upsampler’s interface, the breaking sound is my main problem, it happened at some point. When I change from DSDx2 to 48(the same as input), it does not happen that often.Becuse of dual aes, the music is upsample to 96, the problem is still the same. (It still happen when I turn on the ‘Clone Mode’.
And I connect them like this:

I] I think I'm seeing a pattern of what is supported by the Switch. Most likely only C-Media based USB chipsets using UAC1 (There is a report that Savitech SA9027 works too). -Either natively (chipset only has UAC1 support) -Configured by manufacturer (chipset has support for UAC1 and UAC2 but configured by the manufacturer to be in UAC1 only) -Via a hardware switch (chipset has both UAC1 and UAC2 but the mode is set through the use of a switch)

And I got this information from reddit, and there are list of DAC works. But I can’t understand this conclusion.
