Just installed 20.04 and only Mono-Sound

I have just installed 20.04 on a 60GB partition of the SSD alongside windows and Ubuntu-18.04.

I did the Update and 309-Upgrades. Everything is good except the sound. I only get Mono and a pretty scratchy version of that when I assign the Sound (Settings > Sound) to the HDMI monitor.

When assigned to the Internal card I get good-Stereo but at very low volume even with the "over-amplification" cranked full.

I rebooted to u18 and the sound is perfect via the HDMI source.

I did some searching and found stuff to try

user@Flex-5:~$ sudo lspci | grep Audio
04:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Device 1637
04:00.5 Multimedia controller: Advanced Micro Devices, Inc. [AMD] Raven/Raven2/FireFlight/Renoir Audio Processor (rev 01)
04:00.6 Audio device: Advanced Micro Devices, Inc. [AMD] Family 17h (Models 10h-1fh) HD Audio Controller

user@Flex-5:~$ pulseaudio --start

I assumed Pulse Audio started as there was no error message, but still only tinny-Mono sound.

ETA: Found this page Pulse-removal and while I have not done anything suggested there, I checked the

sudo rm /etc/X11/Xsession.d/70pulseaudio

Folder and there is no mention of Pulse Audio in the list of files therein. Not sure if that means anything.

Can someone please help me out here?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
