currently roonbridge usb connection does not work properly with RPi 4 or the new firmware on older RPi’s. Both Roon and Raspberry Pi firmware groups are aware.
Sorry to ask, but what are the advantages of an RPi4 as far as a Roon endpoint is concerned? Of course, new playtoys are self-justifying. But are SQ or other features expected to be better?

Unlikely to matter as a roon endpoint. Not roon related, but for example, in the SqueezePlay/LMS context, it is unlikely to matter from the use of an rPi as a squeezeplay endpoint (running PiCorePlayer for example). Even an older rPi is not working that hard as an endpoint. However, one can also run LMS (the server, “equivalent” to roon core) on an rPi using this software. The more powerful rPi will be useful for running LMS with a large library.
And the above is my guess as to why it is unlikely to matter as a pure RoPieee endpoint.
EDIT: on the other hand, I’ve read that there are improvements regarding how USB is implemented on the Pi4. That may or may not matter depending on whether one is using a HAT, etc.
USB hub is not shared with the network adapter, so yes, this is an improvement (in fact, this is why I purchased the 4, as I’d like to use the Raspi via USB on my RME ADI2 DAC. Right now it’s a 3 with a Digiberry Hifi+ via coax).
Didn’t someone run a Diet Pi instance with Roon Bridge successfully on a 4 on this forum?
Is the 3 interchangeable with the 4? That is, can the 4 be used as is with the hifi+?
Yes, I have.
It is running just fine.

Yes, USB and Ethernet are improved. The question is - can you hear a difference? Or, can we measure a difference? I will be taking a look at that when I finally some day get an RPi 4.
it works fine for i2s connections like my allo digione. The issue is specifically related to usb.
here is a link to the thread:
the RPi 4B’s header is identical to the RPi 3B+'s; most hats that work with the 3’s should work fine with the 4’s

I’d say it won’t improve much if you’re using a Hifiberry (I don’t think you need a fast or powerful Raspi for streaming), but with USB there might be less chance of conflicts causing clicks and/or crackles. I didn’t encounter any clicks myself though, when I tested the USB output for a week while I was waiting for my Hifiberry to arrive. However, DSD DoP played with dropouts. I expect this to be solved with the 4.

Hi, I am using USB output.
Just now I have been skipping through different FLACs (44.1kHz, 88,2KHz, 96KHz) and I did not experienced any sound abnormalities …
Hi, wow! what version of dietpi are you running? I thought we had to wait for 6.25 for pi 4 support…
Somewhere in this thread:
I am running 6.25.2 and I think it is a stable release since couple of hours.
I will be running it until @spockfish realses its own image 
Which OS/Kernel version are you running?
If you are using dietpi, note that is is still using an old kernel and firmware version that will not allow you to take full advantage of the RPi 4B’s new capabilities…
With a clean install of raspbian 10 (buster) i run into the issue every time, on every RPi and sd card i have tried.
The simplest way to reproduce it is to enable and disable Roon volume leveling several times while music is playing… would you mind giving that a try?
if you are interested, there are more details in the thread i linked earlier.
Hi,
I don’t which kernel is used by DietPi.
I will check it out later when I am home.
update: it is 4.19.50-v7l+ kernel
I am using only the “Device Volume” in volume settings.
Guys,
I thought an update on the Pi 4 stuff was necessary.
Since this morning I’ve got a booting Pi 4 with RoPieee’s customized kernel. That’s good news, because this is basically the hard part of the work.
This does not mean that I’m done: I still need to adjust some things in the kernel. However, I’m rather hopeful I’ll have a working (beta) image this weekend.
I’ll hope you’ll be patient
Regards,
