I ordered and installed a PCM5122 based DAC to my Pi4 for 33USD. Called Innomaker Hifi DAC Hat. Installation was easy and works OK. I have it more than a month now. Stability - I play Paradise Radio FLAC stream for more than two days without a single drop.
The DAC comes with a detailed user manual with step-by-step instructions and screenshots how to install Volumio and setup the DAC itself:

Two things I like:
- in the signal path there are good quality WIMA foil caps,
- beside the RCA there is a 3,5mm headphone connector with a dedicated amp.
As I see, the design itself is based on te Texas Instruments reference design (see the added headphone amp in the TI pdf)
It also has two local quartz oscillators so it is independent of the PI clock and jitter.
No separate power input - its OK for me I built a linear PSU for the Pi4 anyway.
Uses the Allo Boss driver, so no need to text config anything just use the Volumio graphical interface.
As I searched the forum, there was an earlier post about it, without mentioning the maker:
It is in the List of I2S DACs with no name, also there is a wiki about it:
So nothing new - it just changed from noname to Innomaker…
But it worth its price, I think.
