screenshot of my alsamixer

I had some updates yesterday and since, no app sound on my 18.04. Speaker test works, i her the "left, right" when i change the volume, i can hear the little sound to show the volume has changed. My device is recognized and seems to work but that is as far as it goes.

(DELL LATITUDE E5540 btw)

But Firefox still has no sound, my streaming service has no sound as well. I removed / purged alsa and pulseaudio, reinstalled them and forced it, rebooted, still NOK. I cannot find anything relative to 18.04 or might have searched badly.

Thanks to everyone for future help.

EDIT 15/07/2018: Still no sound from my Firefox and Stremio, sound from online radios in rhythmbox OK. Same issue on Google Chrome

    Have you checked to make sure that pulseaudio is actually running? – starbeamrainbowlabs Jul 12 '18 at 19:41
  • Hello,Thank you for your reply : newton@Newton5540:~$ pulseaudio E: [pulseaudio] pid.c: Daemon already running. E: [pulseaudio] main.c: pa_pid_file_create() failed. I can also listen to online radios from Rythmbox, but still youtube or stremio/netflix don't work! :( – Solid Snake Jul 14 '18 at 15:09
  • Have you seen this answer? askubuntu.com/a/260035/139735 – starbeamrainbowlabs Jul 14 '18 at 21:57

This is strange. I installed Pulse Audio Volume Control AGAIN. I had to start a video on youtube via Firefox. In the Playback tab, i saw the AudioIPCServer with the Firefox icon and there the output was set to Built-in Audio ( HDMI ) I just had to choose Analog output and the sound was back. I hope it will help other Ubunters. Did i not get any answers because my question was too "dumb"? Thanks anyway.

I have a similar issue. I also did not have sound from apps, but I had system sounds. I think the problem comes from turning off the computer with HDMI cable still connected and removing it only afterward.

I solved that issue by reconnecting HDMI cable, setting sound source from analog and restarting the computer with HDMI cable connected. After that, the sound returned and I removed HDMI cable.

My system is Ubuntu 18.04 with all updates.

Had a similar issue. I was able to fiddle around in pacmd to redirect sound output from HDMI to analog-output:

  1. Play sound through the trouble application (Firefox in Solid Snakes case) and leave it running in the background.

  2. Open Pulse Audio via the terminal

    pacmd

  3. list your sinks inputs, the trouble applications' sink should be HDMI , ie.

    list-sink-inputs
    1 sink input(s) available. index: 134 driver: <protocol-native.c> flags: START_CORKED state: RUNNING sink: 0 <alsa_output.pci-0000_01_00.1.
    hdmi-stereo-extra5>

  4. Move the application sound output device via the move-sink-input command. The list-sinks command return the index of my analog-output as 1, so

     move-sink-input 134 1
    
  5. You should now be enjoying sweet sounds, well done!

  6. Getting stuck, type help from inside pacmd

There is also the set-default-sink command. The stat command's output can be used to verify your default-sink
