I recently installed Ubuntu 14.04 from scratch, overwriting 13.10. Ever since then, I haven't been able to play audio in most desktop media applications: Spotify, Rhythmbox, Pithos, Banshee...all of them show that they're playing a song (including a libnotify popup), but no sound comes out, and the application's progress bar doesn't move. Web applications (flash, HTML5 in Firefox/Chrome) can still play audio just fine, and desktop applications that do not use indicator-sound (e.g., Audacity) can, too. The one indicator-sound application that I've found that can play audio is VLC.

ALSA info at http://www.alsa-project.org/db/?f=63b1c39b80f5baa1f37190eea3c4b38bfff322d6.

Any suggestions for how to fix this?

EDIT: Just to be perfectly clear, I do have audio in most applications (VLC, Firefox, Totem, Audacity, etc.). It's specific music applications that are affected. I think it might have something to do with gstreamer (although that wouldn't explain why Totem works).

Try in terminal (Ctrl+Alt+T):

sudo killall pulseaudio

sudo apt-get update

sudo apt-get install --reinstall pulseaudio

sudo service lightdm restart

or if didn't help

sudo shutdown -r now

If you have sound in your guest account, then most likely you have accidentally done something wrong to the pulse audio configuration in your own account. Try removing (or renaming, just to be on the safe side) the pulse subdirectory of the .config directory of the account that has no audio: 

cd ~/.config

mv pulse pulse-renamed

Then log out of your account, log in again, and you should have audio back.

Regarding Banshee media player, I worked out a solution.

In Ubuntu 14.0.3, I (re)installed gstreamer0.10-ffmpeg/-fluendo-plugins-mp3-partner/-plugins-base/-plugins-good/-plugins-ugly/-pulseaudio & gstreamer1.0-fluendo-mp3/-libav/-plugins-base/-plugins-good/-plugins-ugly/-pulseaudio/-x, & everything works well, including video playback.

I had GStreamer extra plugins installed too, but not the GStreamer plugin for aac, xvid, mpeg2, faad. Once I installed it Pithos worked on my Dell desktop computer running Ubuntu 14. I'm piping the sound through an old stereo and like the original post other apps (VLC, etc.) were working fine...
