Lenovo T420 Internal Microphone Not Working
Hello,
I have CentOS 7.1 installed on my Lenovo T420 Notebook. Now I will start to have some online meetings for a software project. In Bios the I/O-settings for camera and microphone are enabled. Camera is working (tested with cheese).
In the audio settings of Gnome perferences I see an internal microphone which doesn’t produce any input. The microphone is also not disabled by the key on the keyboard.
Where can I take a look at?
Thank you in advance Tim

One thing to try is adjusting the gain on the microphone *after* you’ve started your conferencing application. I have to do this with my webcam mic.
Hi Ian,
thanks for your reply.
I found the solution on my own: I needed to add an option model=thinkpad to snd_hda_intel. echo options snd_hda_intel model=thinkpad >
/etc/modprobe.d/snd_hda_intel.conf
Now it is working.
Thanks Tim
