I bought a compact Lenovo desktop to use as the host of MythTV DVR system.

It has rudimentary Intel HDA graphics; speakers/headphones/lineout/mic.

The hardware shows up in the System Settings / Multimedia configuration controls, but the sound tests didn't work.

I started looking in logs and found some clues.

The audio hardware is recognized (var/log/messages):

Any ideas?

Updated post to use CODE tags.

Note: Yes, the sound is enabled in BIOS.

Hello,

can you install "pavucontrol", and test with that to see what it says in the "configuration" tab ?

Thanks!

I installed the package. The configuration tab shows "Built-in Audio" as the device. I have a choice of Analog Stereo [output|input|duplex].

It recognizes that I have a headphone plugged in.

And . . . the headphone jack is giving me sound when I use the test button in System Settings. (First time I tried.)

I'm still seeing errors in /var/log/messages:

Nov 30 18:47:18 mythtwo systemsettings5[7593]: org.kde.plasma.pulseaudio: No object for name "alsa_output.pci-0000_00_1b.0.analog-stereo.monitor"
Nov 30 18:47:18 mythtwo plasmashell[1293]: org.kde.plasma.pulseaudio: No object for name "alsa_output.pci-0000_00_1b.0.analog-stereo.monitor"

Well, it looks like I have sound, errors aside. What isn't working is the pass-through to my TV. Separate problem. This one can get set to solved.

How did you connect your TV, via HDMI ?
I also have that at home, and I had to enable "HDMI audio" all over the place, including my BIOS I think. Eventually you may see the HDMI out in your pavucontrol.

@Bobx001: My old MythBox had a wonderful motherboard HDMI output that carried both sound and picture, and I had to do as you suggest above. It really worked great for going on 7 years, but the poor system just wore out.

The primitive sound circuitry in the replacement PC doesn't send sound over HDMI. That connection is really meant to go to a monitor.

I looked at the back of my TV, and found that one of the HDMI ports is designed for use with external audio. There's a line in jack. According to the dusty TV manual I still had around, thank goodness, I have to edit the connection name so it thinks it is connected to a PC rather than a pure HDMI device. If it works, I am back in business.

IT WORKS!

Line out from the PC, line in to a jack on the TV, edit connection name to DVI PC so the jack is activated. Played a video; got sound.

I'm still puzzled by the continuing error messages, but I guess those are just noise.

Thanks all!

Awesome !
Re: noise, unless you mean just text-noise, and FYI between FC23 and FC25, I had a lot of issues with chirping sound-cards, on several of my laptops and pc's around, but they were somehow solved, at least for me, in FC26.
