In case you still want them repaired, there's a guy online (Nic's Fix) who runs a mail-in $60 repair business for dead first gen HomePods.
Here is a video, more on his channel
And I think it works out to about $80 once you include shipping. Ive got a dead one right now - trying to decide if I want to source air gun to fix it myself or just send it to him. Less than $100 to have it fixed is kind of a steal.
