Launchpad currently recommends translating phonon in Ubuntu RTM 15.04.

No translatable templates available

Either this project has not been set up to use Launchpad for translation, or phonon in Ubuntu RTM 15.04 does not have any strings to be translated through Launchpad. If you think this is incorrect, please see if the subject has already come up under Answers. If it hasn't, file a new question there. Thank you.
