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
