No sound in .mkv after upgrade to Ubuntu 14.04
I had the same problem in VLC today. I just went into:
Tools > Preferences > Audio
Then I had to change output module to
ALSA audio output
Thats fix my problem in Ubuntu 12.04, VLC 2.0.8

I was using Ubuntu 13.10 previously, and everything was working fine. Prior to upgrading to 14.04, I deleted some of the old kernels. Then, once I upgraded, the sound for .MKV was gone. I use VLC, but Totem could not play sound either. Other video files worked fined though.
I thought the issue was with codecs, so I installed all
libav*, gstreamer*, ubuntu-restricted-extras
packages. Still nothing. Then I deleted the rest of the old kernels but it still didn't work.I found a solution, which is using GNOME Mplayer, but this player is terrible - when transitioning scenes, you could see the lines in the video and, on larger files (4gb+) the sound breaks once in a while.
I would really like to be able to play it in VLC. I was thinking the issue was with VLC, since they don't have an "official" version for 14.04, but since it doesn't work on Totem as well, I don't think that's the issue.
I don't think the problem is with codecs, since I installed it, but is it possible that the codecs need some old kernels to work? How could I find out which version I need and download an older version of kernel?
Thank you
