Need some suggestions for a DAC for RPI zero 2w

Curious to know why you suggest USB DACs, are those more likely to receive driver/firmware updates?

They don't need any driver under Linux environments, moOde being such...

I'm not sure where to start but of course Linux uses drivers, they are just mostly built into the kernel. More exotic hardware needs drivers which are not included, so you would rely on open source or on the manufacturer of the hardware device to supply them. 

That is what my entire post is all about. Let me give you a direct example.

moOde 8.3.2 changelog:

Updates and Fixes

• NOTE: Allo Boss 2 I2S driver not working on new 6.1.y kernel branch
  
• UPD: Remove reference to pi userid from SSH header
  
• FIX: Worker startup fails on Pi-Zero due to incomplete "is-system-running" test
  
• FIX: Haveged daemon fails to start on Pi-Zero (arm6 platforms)
  
• FIX: Power and activity LED id names causing LED ON/OFF options to fail
  
• FIX: Clicking on context menu check mark icon displays default moOde cover
  

Notice the first line about the Allo Boss 2 I2S driver? Allo has been quiet lately, and I saw more posts about lack of drivers with the new Linux kernel 6.x. 

I wouldn't mind a USB DAC, provided it uses very common hardware and the manufacturer does provide stable drivers or even better if its driver is included in the Linux kernel.
