The problem with the Pi 3 was that the USB and Ethernet used the same controller, which could lead to digital artifacts (ticks and pops) when using both at the same time. This situation is fixed with the Pi 4. So it’s better, if you are using both the USB and the Ethernet. Lots of people avoided this problem by either
Using WiFi instead of Ethernet, and using the Pi 3 USB out, or
Using an S/PDIF hat instead of USB, along with Ethernet, on the Pi 3, or
Using the Allo USBridge USB, along with Ethernet, on the Pi 3.
None of these workarounds are necessary with the Pi 4.
Yes – thanks for confirming this. What you say makes perfect sense to me, so I wonder why some here seem to disagree? In any case, what I learn here is that if I have a RPi 4 and a (good) DAC, I am all set. Only those who do not have a DAC still need a DAC-Hat for the RPi. And then of course, someone might want to choose to use a DAC-Hat rather than an external DAC, but that would be more a matter of taste.
For some DACs, users experience the same USB performance between the 3 and 4 and therefore the same sound quality. But, it is equally true that for many (including me) that the separation of Ethernet and USB made USB possible (I hated the pops). And, in my experience, using a Pi 4 case with heat sinks also results in significantly lower operating temperature. In my opinion, if you want to use USB, the Pi 4 is the way to go (1g model is sufficient for RoPieee XL).
Not sure if it’s been suggested, but I would highly recommend putting an AudioQuest Jitterbug in the rPi4 USB and then USB cable from DAC in to Jitterbug? They really do make a difference to the sound & not that I can compare rPi3 to rPi4, it made a difference on my Mac Mini when using Audirvana & I have 2 in place on my rPi4, one to a Chord Qutest & one to a Meridian Explorer2 (no HATs) Jitterbug

Common sense is not evenly distributed over the human population.

Bad news is that my original issue with sound is suddenly back without warning.
I have changed nothing in system or software.
So I guess this HAT has an issue with RPi 4
So for now giving up and its going for sale and I replacing it with some good standalone DAC
Harry, Not sure if anyone ever got back with you regarding the Pi2AES working with your software? I can confirm it does work using the Hifiberry Digi+ Pro drivers. I’m running a Pi4 (2Gb version). I’ve tested it with content ranging from 44.1/16 up to 192/24.
Side note: Thanks for putting Ropiee together. I have several Roon endpoints running your software throughout the house. Install and management couldn’t be more simple. Stability is top notch. Donation is on the way!
