Failed to open "ALSA Default" (alsa); Failed to open ALSA device "_audioout": No such

You may be interested to hear that in the soon-to-be released moOde 8, the Audio Config screen has been improved to

• unify the output device selection (I2S or USB device) on one page
  
• allow the selection of an I2S driver by device name (as it is now) or by actual driver overlay name
  

The first is a matter of convenience to the user; the second makes it easy to configure for a device not yet in moOde's device database.

As well, the kernel and its drivers have been bumped to v5.15.23-v7+

Support other OSes? Any hacker can fork moOde's code repository and have a go. It should work mutatis mutandi. That's a lovely Latin phrase which more or less means "once all the necessary changes have been made" without committing to a statement of what those changes actually are. T.B.D. when the attempt is made. 

For example, I and at least one other user tried porting a much earlier release of moOde to a different ARM-based SBC as well as distro. In my case it was a SolidRun CuBox-i4Pro and the Armbian distro. It worked in the sense that I could play music (only to USB devices, no I2S interface is present) but it was a pain finding work-arounds to account for the differences from an RPi and the Raspbian OS of the time. Supporting the result in the long term would have been a nightmare as the different distros evolved in their own fashions. I patted myself on the back and moved on.

Thanks @TheOldPresbyope for an update.

I am sure that can be ported this is Linux after all, but if there are so many distro-specific tweaks it is very difficult indeed and not worth the effort, indeed.


However I am sure that Wolfson DAC from my Rotel A12 can be used and RP4 can play via USB port to it but I am not to that advanced in Alsa, DACs, MPD to make it works. I am just hoping that it will work in the future. There is this website: https://www.horus.com/~hias/cirrus-driver.html where it guides how to make it but I have no luck still.  I am doing something wrong or moOde makes it more difficult.

The wolfson driver described in the link you posted is already included in moOde. Have a look in Audio Config in the DT overlay list. This driver is for a wolfson I2S card though and has nothing to do with a USB connected device like your Rotel.
