Audio and Sound Error In Linux

Audio and Sound is not working in dell systems.

• https://askubuntu.com/questions/882198/no-sound-device-detected

• I realized I forgot to try to troubleshoot pulseaudio, as was possibly suggested by the reaction to sudo alsa force-reload. According to the pulseaudio page, I run

• rm -r ~/.config/pulse; pulseaudio -k

• and I rebooted. Now it works! :)

• Disabling the sound in BIOS the re-enabling it does nothing

• Force-reloading alsa in various ways (e.g. pulseaudio --kill; sleep 2s; sudo alsa force-reload ; pulseaudio --start) does nothing

• Reinstalling all soundbases e.g. with sudo apt-get --purge remove linux-sound-base alsa-base alsa-utils && sudo apt-get install linux-sound-base alsa-base alsa-utils also with sudo apt install --reinstall pulseaudio pulseaudio-module-x11 does nothing
