Dear Maintainer,

I have configured my MPD daemon to output through PulseAudio (the PA
server is running as my local user). After doing so, when the daemon is
stopped (no song playing or paused), the volume displays as 'n/a' in
'mpc status' and is returned as undef by the 'volume' method of the
Audio::MPD::Common::Status class in the Audio::MPD Perl library. I'm not
sure why this is--possibly due to a limitation in the PulseAudio
interface--but it breaks mpfade when the MPD daemon is stopped. mpfade
thinks the volume was changed manually, even though it wasn't, and thus
exits erroneously.

Here is the exact message:

    $ mpfade 0.5 100
    fading up from 0 to 100 over 30 seconds
    manual volume change, aborting fade up

I've written a patch to fix this problem. Unfortunately, it's a bit of a
hack, but it should work. I took the liberty of adding a
debian/changelog entry in my name, but of course, feel free to put my
name in brackets and change the name at the bottom. The patch is as
follows:
