Laptop internal microphones not detected since LEAP 42.2

r_widell · April 6, 2024, 6:44pm

I have an old HP Elitebook 8470P which still works fine for me except that openSUSE can’t find the internal microphones since LEAP 42.2 (the last time I successfully did a video conference). I had issues a few weeks ago and finally decided to see what’s going on.

Exec summary: the microphones work great under Windows 10 & Kubuntu 22.04LTS, but not under any version of openSUSE since LEAP 42,2.

If I try to “Configure Audio Devices” only output devices are shown, no microphones or line-out.

The actual hw is:

I have a vidoe conference with the VA in a couple of weeks and I’d sure like to be able to use this machine for that, so any guidance you can offer will be greatly appreciated.

Thanks,
ron

Have you tried YAST>Hardware>Sound. I recently had a similar problem after an update and found that my sound card (the same one as you have) was no longer configured. Editing it resolved the problem.

r_widell · April 7, 2024, 1:27am

I had tried it in the past, but not with 15.5, so I tried it again.

No joy.

Going into “system Settings->Audio” I still see “Playback Devices” & “Playback Streams”
Doing the same thing in Kubuntu I also see “Recording Devices” (both internal microphones and Line-out)

Note that I tried logging out and back in as well as a full reboot, still no joy.

Thanks anyway,
ron

Show what is reported by ALSA:
amixer -c0
arecord -l

You can try setting the appropriate configuration profile via ‘pavucontrol’ (or ‘pavucontrol-qt’).

trying your last suggestion resulted in this:

If 'pavucontrol' is not a typo you can use command-not-found to lookup the package that contains it, like this:
    cnf pavucontrol

so I’ll let you know what I learn after installing and trying it.

Thanks,

Launching pavucontrol-qt and opening the “Input Devices” tab I see:

No input devices available

I’m not sure how that helps me set the appropriate profile.

deano_ferrari · April 7, 2024, 5:03am

Examine the ‘Configuration’ tab to make sure that the correct profile is selected.

deano_ferrari · April 7, 2024, 5:08am

A quick search online shows results from various distros affected simiarly for those using “Intel 7 Series/C216 Chipset Family High Definition Audio Controller” hardware.

Anyway, let’s examine the diagnostic output from alsa.info.sh…

*Follow the instructions given there.

r_widell · April 7, 2024, 5:11am

OK, so I looked again and actually paid attention.

I saw a configuration tab, opened it and found a configuration for “analog stereo duplex”.

I now se input devices as well as output devices.

ron

deano_ferrari · April 7, 2024, 5:13am

Ok, so can you access the internal microphone now? Not muted etc?

r_widell · April 7, 2024, 5:14am

nk you,
ron

deano_ferrari · April 7, 2024, 5:18am

Don’t forget to mark as solved.
