I have the v2 and it has this issue. There is not a pop (except when it turns on or off) but it still has a delay before it starts playing anything on a sample rate change. I might miss the first sec of a song if it’s a different sample rate then the one playing previously
Edit: and I am using the Thesycon driver. The issues I had with them was I had an older generic xmos driver already installed that was fukin with the installation of the new one. It was preventing me from changing the bitrate and bitdepth from the default 384/32. This was causing issues when using with asio or wasapi in foobar because it would error out because it wouldn’t switch down to the source file.
Edit 2: the Thesycon driver is also an xmos driver to clarify. I have so many USB audio devices (dacs, interfaces, instruments, controllers) that I am constantly in USB audio driver hell so this really shouldn’t be an issue for most people (regarding the conflicting drivers at least).
