Source: alsa-lib
Version: 1.1.3-5
Severity: important
Tags: patch
I was a bit annoyed I could not play any sound on my x32 desktop
any more and today investigated it. It boils down to that amd64
assembly code was run, which, of course, cannot work.
While the fix for that (0011-distinguish-x32-from-amd64.patch)
turned out to be a one-liner, I recognised further problems that
appear on all “new” 32-bit architectures added to Linux because
of them using a 64-bit time_t, so 0009-fix-format-strings.patch
was added.
Finally, I found a minor typo 0010-fix-testcase-typo.patch while
investigating compiler warnings caused by what is fixed by 0009.
Please apply them all *and* submit them *all* upstream. In the
meantime, I’ve uploaded a package built from the attached debdiff
to unreleased, but that will, of course, unsync M-A, which is not
the desirable thing to have.
Thanks!
