Comment 3 for bug 601429

I have installed ubuntu 14.04 LTS WITHOUT internet connection, then I connected to the net and installed miro and I did reproduce this problem: the video started to play OK but there was no sound. (Other players played the same video OK, with sound.)

Previously I installed the very same distribution on the very same laptop while I was online and I did NOT have this problem. Same video played OK, with the sound.

To me this did NOT help:
miro set gstreamer-audiosink alsasink

What I did was:
sudo apt-get purge miro miro-data
sudo apt-get autoremove
sudo apt-get install miro frei0r-plugins libfftw3-bin libfftw3-dev libroar-compat2 slv2-jack libtorrent-rasterbar-dbg ttf-dejavu gstreamer0.10-plugins-ugly libavahi-compat-libdnssd1 libav-tools ffmpeg2theora python-gst0.10-dev python-gst0.10-dbg python-mutagen-doc python-pysqlite2-doc python-pysqlite2-dbg

(This was the list of "recommended packages" when I reinstalled miro.)

now the sound is OK.
