Screenshot of sounds setting showing the sound volume locked at 0 and the only audible default sound.
** Description changed: In Ubuntu 22.04 LTS Software & Updates I had the 'Pre-released updates - (jammy-proposed) checkbox checked. An 'important' software update was + (jammy-proposed)' checkbox checked. An 'important' software update was installed and immediately thereafter, during boot sequence the PC is hanging at the splash screen with the mainboard logo displayed. Only a restart allows to load an older kernel, and I have defaulted Grub to the previous kernel version available in my system. Kernel version installed: 5.15.0.50.56 | 5.15.0.50.50 | 5.15.0.47.51 (this last one selected as default). With the system running the sound has disappeared for all devices (headphones plugged on Xonar Essence STX soundcard, analog headset) and sources (youtube through browser, local files & applications). The volume bar is locked at 0 for every device and the only sound I hear is the 'default' bip in sound settings (picture). I have tried to reinstall alsa drivers but none of the solutions tried can restore the sound.
