Description Mik 2020-06-16 00:46:09 UTC
There is no sound card for main and TV monitors. Speaker is greyout on the taskbar and Audio in system settings is empty. This bug is present in Ubuntu 20.10 (Kernel ppa) and Manjaro KDE unstable.

Reinstalling PulseAudio did not help and pavucontrol stalls.

$ pavucontrol
Establishing connection to pulseaudio. Please wait...

$ lspci -v | grep -A7 -i "audio"

5.7-3 Stalls at splash screen first line (boots slowly): Lost the installation. Kernel ppa 5.8-rc1 daily has the same issue: No Sound Card.  

Same ball game In Arch Linux, manual installation takes 60-90 minutes. Reverted the BIOS (May update) to previous version today. I will take a break on Windows now.

I'm sending a fatal error each time 14,15,16 and 17 of June:

ubuntu-bug -s audio

All good with today's daily Kernel:

pulseaudio --kill && pulseaudio --start
