use roon playing random songs, any sampling rate not have 0.2sec delay ,and my vox is always connect not have relay sound,except change sampling rate like 44.1 to 48 or 96K

my hub is set upsampling DSD512

Edit: roon is not use any upsampling
Strange. My Hub is set to PCM upsampling, I'm using speakers instead of headphones, and without Roon upsampling I still get the delays constantly. Guess you're lucky.

I'm glad that my workaround (partial Roon upsampling to 192k) now works with the USB input. Then I get no clicks/delays and I prefer USB over SPDIF in my system so at least that's possible now.

Got a response from Nicolae. They will check the USB input but it could be that the remaining issue for me is Vox related. It's a known issue that the Vox will trigger relay switches whenever the source sample rate changes, even when the Hub does upsampling. The Vox will mute for a little while so it could be similar to the 0.2s issue. The next Vox firmware will fix that issue so I'm just going to wait for that update. He also mentioned that the next firmware for the Vox could even be the next major update (named Torpedo).

Hello, if someone of you (in Europe) is looking for a very good i2s cable to use with Rockna/Audiobyte devices...I have a spare one, 50cm, of this:

The cable is very good and price/quality is unbeatable. It was a good improvement over a cheap HDMI AQ cable I was using.

I can sell it for about half price, if you are interested.

There is an updated firmware on their support site dated 29/04/2022. Adds 768k pcm support to I2S.

Since your Fpga is 1.41 use FW 153_276_119.

Support site is at: https://support.audiobyte.net

May need to register your unit for download.

Hello everyone, I am still very happy with the HUB. Simply an amazing streamer!

Do you guys have any news about the following implementations?

- Application support for the HUB (Android/Apple)

- A way to power on/off the HUB remotely for "Non-Zap users"
