I have no idea if this is useful - hostname = 192.168.0.229 2a02:1810:1532:1900:1804:69c3:a2e:8f4f 2a02:1810:1532:1900:1d39:1c4:f800:fc5b

Using very simple language, is it possible to determine the cause of my problem and the steps to take in order to solve it?

If further information is required, let me know (detailing the steps I should take in order to retrieve it).

I look forward to feedback that a newbie can understand and implement.

Thanks

See if these help...

copy and paste this into a terminal then reply with the output in a code box....use the "Go Advanced" to reply to more easily see the code symbol. Its the HASH # symbol

You could do a search for this....

How did you get that hostname?
It does not look right

reply with output of
2) How do you want sound?
we are not mind readers.....describe the output device and cables

eg I only want laptop speakers
I want laptop speakers and 3.5 mm headphones
I want bluetooth headphones
headphones that use usb
sound thru monitor speaker using hdmi cable.....etc etc

3) pulseaudio (PA) at first glance is not installed properly ....but you can get perfect sound without it.
but you need alsa installed.
paste the output to

hint....if you want laptop speakers you will want analog
if you want bluetooth....you will probably want PA installed and running

Thanks ferrari - however, I should have pointed out that, prior to posting my question, I scoured the net and have visited just about EVERY site available regarding this topic (including the 2 you suggested) with no luck.

I have sound output only through the use of EXTERNAL speakers. However, if I'm going to eventually migrate to Linux from Windows, I'd like to have the 'full experience'.

Once again, thanks for your input. The search for an answer continues...

Does this help?

So the information you shared in post #5 shows that the driver is loaded and the ALSA layer appears to be ok, although I note no headphone output device listed. It might be useful to see what is returned by
It may be that a particular driver option is needed to get the headphone output recognised/active.

We should also find out why pulseaudio is not running. The output snippet you shared from your first post showed that it wasn't running as expected....
Try starting it (as user) from a terminal...
and capture/post the output here. (You can do CTRL-C to terminate it first.)

What does the following return?
Again, post the output here.

BTW, sometimes the existing user PA configuration in ~/.config/pulse can cause issues and needs removing first. It will be recreated when pualseaudio is restarted.

FWIW, a quick search of your audio chipset '8086:a348' and 'headphone snd_hda_intel' returned result including this launchpad bug which may also be relevant to your situation...
https://bugs.launchpad.net/ubuntu/+s...r/+bug/1807138

I also searched for 'Cannon Lake PCH cAVS' audio hardware which turned up this Linux Mint thread.

In particular
The OP in that thread reported success using that driver option.

As indicated in my previous post, sound output IS available when using external speakers (??)

I hope the above is of some use to you.

Again, many thanks for your interest and input!

Please forgive the above threads - obviously copy/paste is ineffective.

I meant to show that all outputs are 00.

You don't execute it directly. You modify /etc/modprobe.d/alsa-base.conf with an editor as root.

The 'Headphone' level (post #10) looks to be right down? For posting such info here, amixer might be a better option.
