[ubuntu-studio-users] No sound during video playback

[leo]

I've run into reoccurring no sound problems the past few months.
I'm running Ubuntu Studio LTS 12.04.5 64 bit

Thanks for your replies, sorry for not being more helpful so far.

I tried logging in as guest from a fresh boot, but guest user could
    not access any of the drives with videos in, nor could I mount them
    as sudo was not allowed.

Then I logged out and back in as my normal user account, and tried
    opening a video with Totem (the default video player) and it worked
    perfectly, with video and sound. I also tried with VLC and it
    worked. I also opened Rhythmbox and it played audio files okay.

So for no apparent reason it seems to have fixed itself without me
    actually doing anything other than logging in as guest before
    logging into my user account.

It could just be an intermittent problem of course.

                  No clicking of play again does anything.

                  Audacity, which I need for editing audio files.

My no sounds (Internet, e.g., YouTube; Ardour playback; wav files playback) problem seems to occur after 
  package manager updates. Which package updates appear to be the culprits, I don't know.
Also, sometimes after playing back files through softwares such as VLC, Audacious, and Audacity gives me the same resulting no sounds scenario.
In each case, why I don't know, I get my sounds back to normal by opening ...
  Applications Menu > Media Playback > PulseAudio Volume Control (PAVC) >Output Devices tab > Built-in Audio Analog Stereo
At that point, even though I can see the horizontal left and right volume displays moving along with whatever sound I'm playing, there is no audible sound.
Then I click the green button with white checkmark...and voila!!!! My sounds return right there and then.
I'd like to also point out that after clicking that button, it gets very slightly either light grey or darker grey and is extremely difficult which is which.
Hope this helps. ~Leo
