Anyone know if this device works with the ps5?
To output 5.1/7.1 digital audio via the ps5s usb port trough this device. I would like to go U-DIO8 - ps5 - Genelec SAM.Do do what?

The jitter is almost certainly because the XMOS implementation MiniDSP uses synthesizes the audio clock from the XMOS master clock, and doesn't do it particularly well. It's probably the same issue that other people have noted with the MiniDSP USBstreamer.
The RME Digiface is cheaper (at least where I live) and you get RME drivers including TotalMix. It has more features (headphone out, and you can record with it), and probably less jitter as well.
I wonder if the unit works with Raspberry Pi + Kodi usb output. Anybody has a direct experience with this setup?
Getting ready to place my order. I have no interest in upsampling, but curious if you ever found a resolution to this issue.I came up with a very simple test for the U-DIO8. I connected the “OUT 1-2” SPDIF RCA connector to the “IN 1-2” SPDIF RCA connector and send a 192 KHz test signal via USB from a Windows computer through this loopback. Just the U-DIO8 connected to the PC, its all digital (no DAC or ADC) and for the SPDIF portion of the signal path the U-DIO8 is talking to itself. Here is a photo of the setup:

I used a RCA connector to join the OUT and IN cables. I used REW on the Windows PC to generate a 1 KHz sine wave and send through this loopback test and here is the received signal:

The SPDIF signal gets so distorted, that the U-DIO8 can rarely decode and extract the sine wave data. So, there appear to be some significant signal integrity issues in this Minidsp cable and U-DIO8. It can't even talk to itself.
Looking back at @amirm 's original review, I see that he tested at 48 KHz and was testing the AES/EBU variant. The balanced signal pair and differential receiver might help hide some of the signal integrity issues of their design (and the APX555 may be very forgiving), but with a SPDIF RCA unbalanced connection you need to step up your game.
I am hoping that this is just a bad cable or unit, so don't take these test results as representing minidsp products. I really like their products and I think the team there is the best -- they have been very helpful and nice.
could be the unit is not designed to make digital loopback like this, it needs the input to be the master clock.I came up with a very simple test for the U-DIO8.
