My internal microphone on my thinkpad t440s is not picking up any audio on Ubuntu 15.04. For reference, here is the output of lspci and my kernel I am running.

philip@philip:~$ lspci

00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09)

03:00.0 Network controller: Intel Corporation Wireless 7260 (rev 83)

And here is my kernel

philip@philip:~$ uname -r
3.19.0-15-generic

Would anyone have any suggestion of things to do?

  • Perhaps post a few GUI screenshots from ~ system > sound(s)? I'd assume the mic is not "switched on" or selected properly. How did you try to test it? What does arecord -l say? -- For extensive troubleshooting on this see http://www.troubleshooters.com/linux/sound/sound_troubleshooting.htm and also try arecord -d 10 /tmp/test-mic.wav followed by aplay /tmp/test-mic.wav from http://linuxconfig.org/how-to-test-microphone-with-audio-linux-sound-architecture-alsa – nutty about natty Aug 17 '15 at 09:26
  • 'Here is a screenshot from my sound setting for input of my microphone. http://i.imgur.com/NXup0wE.png Now the problem is when I make any noise, or yell at the mic, there is no sound that moves on the sound spectrum graph. This is how I tested it, as well as running it on skype, as well as the sound recorder. Here is the output for the commands, and when I ran aplay I did not hear any of the sound that should have been heard. http://pastebin.ubuntu.com/12109618/ – philipballew Aug 17 '15 at 17:12
  • Judging by the looks you can "mute" your mic input with Fn-keys. Have you tried toggling this "mic mute" ? – nutty about natty Aug 18 '15 at 07:06
  • By a few GUI screenshots of "sound" I meant a few: e.g. also while sound is playing, and also from the "applications" tab (while sound is playing). – nutty about natty Aug 18 '15 at 07:10
