Pulseaudio profiles not available (analouge stereo) so no sound

[shag00]

regression-update bug 1876065
I am running Pulseaudio version 1:13.99.2-1Ubuntu2.1 which I assume is a newer release than 1:13.99.1-1ubuntu3.3 as described in bug 1876065.

I am trying to use and set analogue stereo sound as my default sound.

On each boot Pulse reverts to these available profiles (extract only, full text as attachment)

pacmd list-cards
name: <alsa_card.pci-0000_09_00.3>
...
profiles:
        input:analog-stereo: Analogue Stereo Input (priority 65, available: no)
        output:iec958-stereo: Digital Stereo (IEC958) Output (priority 5500, available: unknown)
        output:iec958-stereo+input:analog-stereo: Digital Stereo (IEC958) Output + Analogue Stereo Input (priority 5565, available: no)
                off: Off (priority 0, available: unknown)
active profile: <output:iec958-stereo>
...

After deleting the files in ~/.config/Pulse and entering: pulseaudio -k, the output changes to:

pacmd list-cards
name: <alsa_card.pci-0000_09_00.3>
...
profiles:
        input:analog-stereo: Analogue Stereo Input (priority 65, available: no)
        output:analog-stereo: Analogue Stereo Output (priority 6500, available: unknown)
        output:analog-stereo+input:analog-stereo: Analogue Stereo Duplex (priority 6565, available: no)
        output:iec958-stereo: Digital Stereo (IEC958) Output (priority 5500, available: unknown)
        output:iec958-stereo+input:analog-stereo: Digital Stereo (IEC958) Output + Analogue Stereo Input (priority 5565, available: no)
        off: Off (priority 0, available: unknown)
active profile: <output:analog-stereo>
...

Having discovered the correct sink and profile one would proceed to make them the default by adding these 2 lines to /etc/pulse/default.pa:
1/ set-default-sink alsa_output.pci-0000_09_00.3.analog-stereo
2/ set-card-profile alsa_card.pci-0000_09_00.3 output:analog-stereo: Analogue Stereo Output, or,
   set-card-profile alsa_card.pci-0000_09_00.3 output:analog-stereo+input:analog-stereo: Analogue Stereo Duplex

Setting the default sink (1) causes no problems but only allows selection of iec958 stereo but attempting to set the default profile (2) and rebooting and opening PulseAudio Volume Control leads to a pop-up window displaying: establishing connection to PulseAudio please wait... In other words PulseAudio is not running.

So in summary I can get sound by buggering around each boot but cannot fix the issue on a permanent basis. This PC was release upgraded to 20.10 yesterday.

This is the 3rd PC in the last several months I have had to spend significant time to get sound working, the others I found a permanent work-around for. All are fairly new, the other PCs are running a Ryzon 3000 and 5000 series CPU and Kubuntu 20.04 and 20.10. Having sound is something that should work out of the box.
