Another sound problem with Cinelerra

[monoRhesus]

Hi everyone, I successfully installed Cinelerra but i can't figure out why I can't get any sound during playback.

* The files I'm using are .mov, and they do playback normally using Totem or Quicktime on a Mac.
* I've tried different Audio drivers and nothing works.
* I've tried arming the audio channels.
* I've researched this forum and have googled the problem and I have no leads...
* I do have sound in .wav .mp3 , other .mov files, movies etc, so I have all the needed firmware/software installed

alias snd-card-0 snd-hda-intel

* Sample rate in Settings --> Format coincides with that of .mov file.
* I must be doing something wrong then, because it doesn't seem to be a general problem...

I'd appreciate any ideas!
