I don’t see any of the Schiit Audio DACs on here: RoPieee | Audio Hardware
Anyone know if they are supported? I have the Lyr with DAC, and want to connect it via USB to a Raspberry Pi 4 B running RoPieee.
Secondly - any recommendation on which memory capacity I need for the Pi? 4GB?
You are never going to regret going for more RAM but if only running Rosie it seems pretty efficient. I went for the 8GB purely because it gives more software options

That list is for native DSD streaming, which is not supported by Schiit. Schiit is compatible with standard USB audio and will work with your Lyr.
What @mSpot said re: DSD.
Your Lyr should work just fine as a USB DAC connected to an RPi 4. In terms of RAM, Ropieee is a very light piece of software and will work with even a 1 GB RPi 4.
There is no reason to get a Pi with more ram, as RoPieee won’t use it and doesn’t need it to run well. (I have measured ram usage over time, using a mixture of pi3, pi4, w/ displays, XL and so forth.)
The one spike in the screenshot is NOT RoPieee.
I’ve been running RoPieee XL and Volumio on RPi 4 with 2 GB for the last 2 years, and works fine. RPi 3 would also work.
