OK, so, unsurprisingly, the beta has the same issue.
I tried jaunty's kernel, 2.6.30-9 (the one that used to work on the 6/25 daily) and 2.6.30-10 and I got absolutely no sound.
(whereas with an an up-to-date kernel there is "at least" very low and distort sounds on my headphones.)
I also tried with kernel 2.6.31-13 and 2.6.31-14 but this time the original bug came back (see bug description for symptoms)
I don't know if these tests are relevant, pre-2.6.31 incompatibility might be caused by some user-space change or other.

What else can I do ?
