Input sound random detection.

Hi,

Thanks Tanu for your feedback.

On these pictures you can see the sound level at 100% display on top bar 
sound widget and at Gnome sound settings.

Sound widget:

Sound settings:

Video showing, how the sound input is starting to work, after a bit 
change on input sound level volume.

Also i attach pactl output when sound input isn't working.


Thanks in advance.

Gustavo.

In your original explanation, however, you said that the input volume is 100% when it's not working, and setting the volume in sound settings to 20% makes it work. It would be good to know in more detail what you mean by "sound settings" and "input volume". You could upload somewhere a screenshot of the sound settings when it's not working and input volume is 100%, and while the sound settings are open in this state, run "pactl list" again and send it to the mailing list.
