** Description changed: My output sound device "Lenovo Family 17h" worked well in Ubuntu 20.04. - "System => Sound => Output Device" shows only "Dummy Output". device: IdeaPad-5-14ARE05 + Since shortly it stopped working and only showed: "System => Sound => Output Device" - "Dummy Output". Checked it with different kernels and it is not kernel related problem since upgrade of libasound, so we set back to older version cat /prod/asound/cards - 0 [Generic ]: HDA-Intel - HD-Audio Generic - HD-Audio Generic at 0xd04c8000 irq 90 - 1 [Generic_1 ]: HDA-Intel - HD-Audio Generic - HD-Audio Generic at 0xd04c0000 irq 91 - 2 [acp ]: acp - acp - LENOVO-81YM-IdeaPad514ARE05-LNVNB161216 + 0 [Generic ]: HDA-Intel - HD-Audio Generic + HD-Audio Generic at 0xd04c8000 irq 90 + 1 [Generic_1 ]: HDA-Intel - HD-Audio Generic + HD-Audio Generic at 0xd04c0000 irq 91 + 2 [acp ]: acp - acp + LENOVO-81YM-IdeaPad514ARE05-LNVNB161216 we figured it to be no pulse problem but with alsa solution: sudo apt install libasound2=1.2.2-2.1 libasound2-data=1.2.2-2.1 libasound2:i386=1.2.2-2.1 libatopology2=1.2.2-2.1 to prevent from upgrades again: echo libasound2 hold | sudo dpkg --set-selections
