[SOLVED] no sound in video or audio
by Pedroski from LinuxQuestions.org on (#4SEJP)
I use the Ubuntu 18.04, I keep it updated.
I tried to play an mp3. No sound. Mute is not ticked.
I go to sound settings, click "Test sound" It plays "front left, front right"
I press Fn and F8 or F7 to increase volume or decrease volume. I hear the little sound which accompanies that.
But no mp3 or mp4 will play with sound. Yesterday it was working.
I've noticed, sometimes, after I have used an hdmi cable, the sound does not work.
I go to sound settings, click On the entry on the left in "Play sound through", which is "Speakers built in audio" then it works.
That does not help this time. No sound from Videos, Audacious, Audacity, vlc.
Any tips please?
