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
