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

I have to do this with my webcam mic. -- =======================================================================Ian Pilcher arequipeno at gmail.com -------- "I grew up before Mark Zuckerberg invented friendship" -------- ========================================================================
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.
