==================== This is a repost of a thread I started in the Multimedia forum five days ago. Since it didn’t get any response (and I discovered I was posting in the wrong forum) I’m reposting it here in the hopes of getting my issue resolved.
My laptop’s internal microphone doesn’t work. I ran alsa-info.sh to collect data about my configuration. Hopefully it helps diagnose the problem.

Since the full info dump was a little bit too big to post here, I put the file in its entirety on Pastebin. I also noticed that KMix doesn’t display any inputs/outputs…
I’ve been out of country with very limited internet access and no one else chimed in.
Thanks for the information you provided, but I confess I am not smart enough to understand how it can help. Instead I need the information that is requested to be provided from the multimedia stickie (quoted section): Welcome to multimedia sub-area
I note you provided a partial output of /usr/sbin/alsa-inf.sh, and then a paste bin of the full. Did not the app automatically paste the content to a URL ? I think the images in the quoted multimedia stick make it pretty clear how to do that: Welcome to multimedia sub-area
Again, I would like to try help , but I need more information.
While waiting for the rest of the information I took a look at your mic. You did say ‘internal’ mic ? I’m puzzling over your mixer settings. Look at the mixer settings (especially those I highlighted in red)

Is it possible to capture sound with the internal mic when not selected, when capture is OFF, and when capture levels are at 0% ? I’m still learning pulse audio, but its it possible that will also prevent even pulse audio from recording ?
Could you look at selecting the ‘internal mic’, and changing the capture from OFF to ON, and moving up the capture levels higher than 0% ?
Wrt openSUSE-11.4 I like to use the application pavucontrol (it needs to be installed extra from oss repos) for controlling my mics and volumee and ensure the selected tabs show all devices and all streams.
Thanks for mentioning pavucontrol – this tool helped activate the microphone simply by unmuting it. I’m definitely keeping this piece of software in my tool belt, because KMix doesn’t let me configure my audio devices for some reason, as shown above.
I don’t know why. Was it a design decision wrt pulse integration in KDE ? Was it a ‘fall out’ of pulse being used on KDE that was unavoidable ? I simply do not know.
I do know that some KDE uses have taken to using the xfce mixer as a result of kmix being less useful.
But like you, I find pavucontrol more useful.
Reference ‘input device’ in pavucontrol, I recommend you change “Show” from "All except monitors’ to “all input devices” . Also, in the ‘Recording tab’ change to all streams
Does the internal microphone work now ?
That still shows things muted wrt the mic, but its possible Pulse audio can ignore that amixer output ? I don’t know. I’m curious to read of the results of your pavucontrol efforts.
I see internal mic is selected as source 0. Its strange capture 0 is flagged as muted, but it seems the ‘amixer’ does not fully reflect the settings as applied by pulse:
