Ah, sorry, I didn't realise you had it all working on the bench and just needed this last piece to finish it off.Sorry, thought we’d be above petty passive aggression on this page. As you may have read, I have more or less fully described the concept of what you link to, having a complete understanding of the circuitry involved. I simply asked how to achieve Sine Waves with Raspberry Pi, not how to make this thing from the bottom up.It's going to be really hard for you to do since you don't actually seem to know anything.
Here's a patent document describing something that appears to match what you are looking for:

If you’re going to be snarky, at least make sure to add something worthwhile to the discussion.
Since you are using a Pi 4 you could try the pigpio library:
