Hi Tanu, thank you for the feedback. No, i can't break the microphne after it started to working. The sequence is following: 1) Boot the laptop. 2) Mic with conf apps, like skype and Hangout isn't working. 3) Mic on other sound apps type, like QArecord, working well. 4) Changing volume input level on gnome settings. 5) Mic start to working with Skype. 5) Change the volume to 100%, and MIC still working. 6) Reboot the laptop, and back to beheavoirs from step 1), I wonder why, mic is start to working if change the volume from gnome-settings ? I tried to change de volume with: amixer set Mic 20 on or pacmd set-source-volume 1 13106 pacmd set-sourece-mute 1 0 and without effects. Is like, the settings should be changed from a gui apps, may be something related with a dbus signal ? I'm going to see the source code of gnome-settings, to see what it does to change the volume, and see if a can find a clue for this side. Do you have another test, i can do ? Thanks in advance.
