Rhythmbox playing without sound

I am quite sure this is a rhythmbox bug. (Bug 977866)

Instead of reading the mp3 files directly from the share I added the share (//fileserver/music) to fstab and mounted it to /home/dries/musicshare.

When I open the same MP3 in 2 different ways, one will play without a problem, one has the described problem:

smb://fileserver/music/song.mp3 does not play /home/dries/musicshare/song.mp3 plays without a problem..

To me this is a solution, I have no problem, mounting the share directly..

I encountered the same problem. Go to sound settings --> applications and check if Rhythmbox is not muted.

Following the instructions here to reset Pulseaudio config solved the issue for me:

rm -fr ~/.config/pulse/ 
pulseaudio -k
