Hello, this looks good to me. However, the package now cannot be installed together with the "normal" libcanberra package, as both contain lib/libcanberra.so.0.2.5. I suppose that is okay?
Would you mind sending a patch formatted with "git format-patch", after committing to a local branch with the usual commit message? Then your authorship will be preserved to posterity; otherwise I would look like the author when I push. And I suppose there will be more patches from you, so it is probably worth the effort to get used to this workflow! Thanks, Andreas
