The Links were to show the kernel and ALSA patches that are already included in your system
The Pulseaudio data shows that the Hifi Profile and the Ports from alsa-ucm-conf are in place
The command suggested to is only a temporary fix to get audio working again when audio resets to Off
PulseAudio will continue to switch to Off because the HiFi profile is shown as available: no
If the Hifi profile is changed so it is detected as available:yes or available:unknown then PulseAudio will not try to switch away from the working profile
Try this to adjust PulseAudio configuration
(previously suggested in this forum post - #15 by philm)
Open Pulseaudio configuration file for analog-outputs in a text editor
sudo nano /usr/share/pulseaudio/alsa-mixer/paths/analog-output-lineout.conf
find this section:
[Element Desktop Speaker]
switch = off
volume = off
change it to this:
[Element Desktop Speaker]
switch = on
volume = on
save changes Ctrl + O and exit nano Ctrl + X
Then reboot system and check the Pulseaudio Profile and Ports in pacmd list-cards
