Bug Description

My sound settings for output is showing Digital Output (S/PDIF) while I am thinking this should be (Speaker) however, there is nowhere to change it. The Alsa mixer confirms S/PDIF zero audio levels and this cannot be changed.

It means you should try the workaround suggested in bug 946232
Specifically: "For those of you who are missing a speaker port, edit /usr/share/pulseaudio/alsa-mixer/paths/analog-output-speaker.conf and comment out all lines that start with "required-any"."

If the workaround is successful, this bug is a duplicate of that one.

^I forgot to mention that you need to restart pulseaudio after you edit the file. This command will do it:
pulseaudio -k

Dave: Re posts #s 8 and 9, thank you. I found five of the "required-any" lines and commented out all five and did as you indicated in post #9 (I even rebooted the laptop) but still no sound. I have attached a screenprint of my sound output.

Raymond, is there something I need to do from all you have posted?

Mmmm...., gents, I was looking at the last screenshot of my output settings and had a hunch. I decided to move the output volume to about 75% and still had no sound. I moved it to about 80% and still no sound. I moved it to 100% and bingo, there was sound! Why would there be no sound at levels lower than 100%, I have no idea. I actually tried it twice, and got the same result on both occasions.

I then went back and removed the ";" from the "required-any" lines, restarted pulse audio, and I had sound. So it seems that the problem was with the audio levels being less than at maximum. That doesn't make any sense to me seeing that at that level the sound was so loud that I had to quickly mute it.
Maybe something is a bit buggy but at least I have sound on the laptop.

Thank to both of you for taking the time to help me try to resolve this.
