You have been subscribed to a public bug:
Sometimes (twice this month) I can't hear any sound on my headphones.
When I remove them and use builtin laptop speakers, I can hear the
sound. Changing volume using the sound indicator doesn't solve it. Even
restarting computer doesn't change anything.
I found a solution by opening "Sound Settings" and set volume to
"unamplified". Afterwards the indicator works without problem.
I am not sure if this is 100% bug for Sound Indicator, pulse audio or something
else, but this is not desired behavior. I would be glad to provide you
additional information if you have any questions.
