[SOLVED] Internal microphone of Thinkpad T410s doesn't work in F16 64

[wu_qso]

The internal microphone doesn't work after update of F16 recently. I'm using F16 x86_64 system on a Thinkpad T410s. What's the problem?

Here is a potential solution. It is for Thinkpad T520, but it should more or less work for T410 also.

Hope this helps.

Use "sound settings" from the to panel tool.
Select the "hardware" tab.
You probably need "Analog Stereo Duplex"

Steve, this does not work (for me - at least). I have had this setting and Fedora never seemed to detect the internal microphone. However, once you edit the alsa file as given in the link, it works. Well, at least in my experience.

The relevant section from the blog is below.

Switch to root and open config file /var/lib/alsa/asound.state

See differences in control points 6 to 11 in file linked below. Generally – values have to be set as true or higher than 0 etc.

After editing and saving run this command: sudo alsactl restore (and check if it works)

Again, this is the only thing tweak that worked for me. Might be different for others.

Hmm - the alsa-project.org website is broken today.
I *think* this implies a problem in the alsactl_init files - not clear.

I did as you suggested but when I run 'alsactl restore', the system echoes as,

Found hardware: "HDA-Intel" "Intel IbexPeak HDMI" "HDA:14f15069,17aa21a4,00100302 HDA:80862804,17aa21b5,00100000" "0x17aa" "0x215e"
Hardware is initialized using a generic method
alsactl: set_control:1328: failed to obtain info for control #6 (No such file or directory)
alsactl: set_control:1328: failed to obtain info for control #7 (No such file or directory)
alsactl: set_control:1328: failed to obtain info for control #8 (No such file or directory)

What's wrong?

Could you try this as root

alsactl -f /var/lib/alsa/asound.state store

The above code was taken from Arch Wiki - ALSA guide on ArchWiki

I made the change to the file "asound.state" and used the command 'alsamixer -c0 -Vcapture' to enable the internal microphone. Thank you for your help!

Ah! Does the microphone settings stay after you reboot or do you have reset everytime you switch on the system? That's something I would like to know ..

[wu_qso]

Yes, the microphone settings stay there after I reboot the computer. So I don't have to reset them everytime I switch on the system.

[nonamedotc]

Ah! Wonderful. I will also do the same! Would you please mark the thread if you think you query is resolved.

Cheers.

Works great, thanks!

This should be the default setting, or auto-detected, I guess.
